Its odd how every "Intro to Calculus" video I see fails to define exactly what it is. I remember Day 1 of AP Calculus, the teacher drilled it into our heads: Calculus is the mathematics of motion and change.
That’s really funny actually because I just watched a video that’s supposed to serve as an intro to the idea of calculus and one of the first things it said was how calculus is the math of change. (first calculus video I’ve ever watched too lol). I guess you just gotta find the right one.
Been out of high school for years and I’ve been looking for this cause I love math. Thanks. Ur a legend.
I was brushing up on my calculus today with The Organic Chemistry Tutor, and his explanation helped connect the dots for me that my professors did not explain.
Derivatives shows you the predicted instantaneous *rate/slope* at a given point; integration shows you the *area* at a given section of an equation.
My assumption after learning calculus 1 and 2 was that derivatives were only used to prove that integrals work, not something tangible. Once I understood that vital connection, the word problems suddenly made a lot more sense and why I sometimes used one versus the other.
Motion and change is one application of calculus, and usually the easiest motivating example to use for introducing the topic, but it isn't the only application. Finding areas of exotic shapes is another application.
There are also applications in subjects like statistics that have nothing to do with motion.
Thank you!
First principle of Calculus:
Calculus is Awesome 😎
Me: got! Let me write that down.
That’s literally me in AP calculus. It can be fatal not to right everything down sometimes so I just have a habit of writing everything the teacher says and writes

Thank you, now i understand why most of visual demonstarations use the "find the area" as example
Ephesians 6:10-18 says, Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; and your feet shod with the preparation of the gospel of peace; above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God: praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. The bible is no old book. You have to really let Christ open your eyes; to see the world in shambles. Many people say it's a religion to lock up people in chains, and say it's a rule book.. why? Because people hate hearing the truth, it hurts their flesh, it's hurts their pride, it's exposes on what things have they done..people love this world so much, s*x, money, power, women, supercars.. things of this world. Still trying to find something that can fill that emptiness in your heart. You can't find that in this world.. only in Christ, the bible is no chains, it's a chainbreaker. Breaking your sins into pieces... Repent now, and turn back to the true Lord only.. God bless.

I passed pre calculus and I’m getting myself ready for calculus 1. So excited!!!
@@Substantialstem800Good luck. Hope you'll do better than me.
I wished I took pre calculus before calculus 2 cause I failed now i got to review for the next semester
I am in calculus 2 with out knowing anything
I believe an absolute must for college mathematics is math induction. That should be one of the first priorities it’s beginning of the math classes first semester
Doj
Hell yes a bunch of numbers and I still don't know what to do with them thank you so much sir
Emphasize why Calculus is so awesome in one minute. The understanding part is hanging out somewhere else in a mysterious place. Math teachers aren't good at explaining math because they are too excited about being good at math to have to explain it to those who are not. It's an inverse proportional equation. What happens is that students who are bad at math only hate math until they become good at math. The one's that make it, end up loving math; the one's that don't continue to hate math. It's like a cult that once you join, you go: I see that now.. it's all so logical. But the one's that don't, continue the underground movement of hate against math. Very few, if any math geniuses understand why math is so hard to many people. They only seem to understand why it's so simple to them. The true genius understands both simultaneously. Good night.
Most people who are good at things naturally tend to not understand how others are unable to do them also. If you are naturally good at something you do not think about how you learned it. That applies to all things.
Sometimes, people are blessed to understand that others see or feel things completely different from themselves. They try to think how others are thinking and how they can guide them to being able themselves. Those people are rare.
same with tech (hardware/communications and programming/networking) teachers and classes. some of these teachers just zoom through the material and just marvel at how genius they are themselves but just leave most students behind.
funny that i learned one very important thing from my breakdancing buddy who is now a teacher at a college...but he told me this over 10 years ago before he was a teacher. "you dont truly understand something until you can EASILY teach it, and people get it". but then u can talk about it still on a higher level with people who are very experienced/educated.
While it seems too easy just remember: integrate to find area under the curve. That x^2 might represent the weight of a cable. The integral, then, is total weight between two supports at 2 and 5.
Cables don't hang in the shape of parabolas. That is a common misconception that high school algebra textbooks give for "examples" of parabolas.
@@carultch i appreciate your precision... my errant though was just a crude example to give calculus credibility.... to reveal ita beauty.
@Prodigious147 thank you, I think. But, no, I'm not gpt. I vividly recall when I first learned how complicated problems like suspended cables could be easily calculated with calculus....
@Prodigious147 ok
@@josedanielsanchezvidal8936 I know what a catenary is.
Thanks I knew nothing about calculus but after watching this a few times I actually tested out of having to take Cal 1! thanks
So basically breaking down a shape into smaller pieces again and again until it matches with the area of the shape then use the formula on each shapes that you broke down and you can add that up and get a accurate estimated area CALCULUS IN A NUTSHELL
That's the way it was explained to me in the 8th grade.
I feel like there's more than enough space to write the rule
Integral of Xⁿ=(Xⁿ⁺¹)/(N+1) to get X³/3 to give beginners an easy win. If you're looking for ideas, your next short could calculate just how much space.
"An easy win"?
Sarcasm much?
@MrUndersolo Nah, not really, except for my comment about there being more than enough space to add the formula. There are no free rides in math, but it gets easier if you learn the basics of the game. That means anyone who wants to understand this video must understand basic algebra, but if you don't include that formula they won't have a chance.
I still don’t understand how you got x^3\3 instead of x^2
Here's the step-by-step solution to find the antiderivative of x^2:
Given:
f(x) = x^2
Step 1: Apply the power rule for integration.
∫x^n dx = (x^(n+1))/(n+1) + C, where C is the constant of integration and n ≠ -1.
In this case, n = 2, so:
∫x^2 dx = (x^(2+1))/(2+1) + C
Step 2: Simplify the expression.
∫x^2 dx = (x^3)/3 + C
thank you chat gpt

this tutorial so good I learned the entirety of calculus in 1 minute
thank you for the help bro i was thinking of taking Calculus course but after seeing your video i understood the the whole course
😅😅
Calculus is amazing. Anybody that says otherwise... Is good in my books :)
I love mathematical logic the most though!
I’m not particularly good at math but how did he end up with x^3/3?
integral of x²
Integral of x^n = (x^n+1)/(n+1)

why is it exponential by 3?
I’m in my sophomore year of high
School rn idk why but I just wanna learn calculus seems interesting ngl
I recommend the video by organic chemistry. I'm in Pre Calc right now and it gave me a nice look ahead into what things will be like next year
Racist.
@@Revelian1982 Nice joke, really appreciated that
I find it fascinating but I'm not doing this kind of maths at school
Thanks for this succinct explanation.
Jokes.
You can estimate the area:
x = 2->3 y = 4->9 av = (4+9)/2 = 6½
x = 3->4 y = 9->16 av = 12½
x = 4->5 y = 16->25 av = 20½
So the estimated area Ae = 6½+12½+20½ = 39½ not bad.
The estimate is obvious too high because of the curve of y = x² ... the real value of y(2½) = 25/4 = 6¼, not 6½
Now again with real values:
y(2½) = 6¼ y(3½) = 12¼ and y(4½) = 20¼
with a total estimated area Ae = 6¼+12¼+20¼ = 38.75
Getting closer to the real area.
Making more and smaller steps in x will result in better estimates. Using a computerprogramm or Excel sheet will do the trick without integration.
It takes 100 steps to get 39.000
Literally this is not only explaining how calculus is so simple but why we even do it actually so simple. Why aren't we taught it like this? I think we taught it in like a way that's rushed to get as much information in but it's not even that much information to just say why we do it and just so easy
Definitely
Thank you 😊!❤ I have a upcoming competition and I needed to learn calculus in a month and because of you I got it in 1 minute 😭♥️
My mind was blown when I saw formulas that I have to use while I’m in confusion
Love the graphics --do you have practice exercises with your lectures to buy?
Of course the answer is 39. How did I not know that? My brain started crying after the word “awesome.”
Fantastic! Calculus is Awesome!
Honestly, this isn’t that bad of an explanation
Then it is as bad I feared. I'm a moron.😢😆😆
Very simple in my old age 53. I am searching for my retired maths teacher .

In a non condescending way, do you know how to derive a function?
@@orans_ nvm, got it. The derivative of x^3/3 is x^2. He just did it in reverse
How is x^2 ~ x^3?

Please explain why ie the mechanism of why your doing what you’re doing not just calc rules!!

So why exactly are we multiplying the Xs 🤔 subtracting the x points ,dividing by 3, then dividing both sides both times the x points 🤨 and then subtracting them 🤔
How to find areas in irregular shaped objects aka estimate. Thats calculus in a nutshell.
How do you go from x squared to x cubed over 3?

Awesome 🎉
Question: why would we want to know the area of that little yellow part?
I don't understand how people find calculus difficult, it's easier than algebra, (I barely passed that) 😂
How is it easier? I feel like algebra is the easiest.
@@RoyHoy nah-??????
I guess it's easier cause you're smarter lmao
depends on curriculum
@@RoyHoy wait till bro sees group theory
galois theory
abstract algebra
Basically calculus in all about the tangent line. As you might have remembered from Algebra 1 it uses a more complex version of the point slope form quotient which becomes the secant quotient and then the tangent quotient to find the limit and then this becomes the deifference quotient and this gives you the derivitive and its opposite cousin the integral. Then there is the shortened version of the difference quotient dx/dy and the rest in a lot of algebraic manipulation. I took it one time and failed miserably but what I didn’t realize is how much I learned in the process of failure. I have been going over the material again before I retake it and have found that my real problem wasn’t the calculus part of the course it was my failure to intuitively understand college algebra and trig. It’s so cool that if you fail it you might be in love with its complexity like me and be ready to retake it. One thing that makes it cool is the incredible applications of calculus which include space travel. That might get you hooked so Google it and then you can find you are doing simpler but the same basic math they used at NASA to put a man on the moon and the pathfinder on Mars. What kind of smack can you talk about that!
I understood most of it, but I dont get why or how you get :x to the power of 3 over 3.
How was the integral converted to get that answer?
Anti derivative
Add one to exponent and divide by the exponent amount after you add 1
(x^(n+1))/n+1 + C
C represents the constant of integration
Now I get it!
3 semesters in the classroom and still don’t get it. Professor was generous with the C-. Should have failed me so I could get a do over in summer school.
As a sixth grader, I will learn and understand calculus probably in a month or less (Probably will take a while)
Love your high hopes and enthusiasm but it’s important to be realistic! If you put in the time, you can understand the basics in a month or so but to understand what’s truly happening, it’s important to grasp, geometry algebra, and trigonometry before you start your calculus journey! Best of luck in your math endeavours!

Oh cool, I am also trying to learn calculus so I can use it for physics, I don't think that there are AP courses in my country. Otherwise I wouldn't learn it, because they do not teach it before really high levels of education in my country. Also I am 7th grade in my country which is 8th in USA lol.

Math explanations always assume you know a certain level of math and I always get caught up on little unexplained parts. I can’t learn from an explanation if I don’t know where numbers are coming from.
Thats epic 😮

How is Y = X^2?
When plotting the graph 📈 the value of Y is equal to X^2. So when X= 2 then Y=4.

Where did you get the 3? It seems to just appear. Is it the LW?
it's some rule you will learn, dw about it for now. you add one
you add one to the exponent x^2 + 1 = x^3.
the three you see is from 2 + 1. The 2 is the squared that's why it's 2
Why would I want to understand things that would result in being employed as a tool , day in day out?
There's no formula for this. So let's use this formula to figure it out😅😅
Why is calculus easier than allgebra for me.
Where did tge 3 come from
What the flipper doodles is that 1st symbol on A=__x2 dx
…and how did it get to x3!?
I get the division part because it’s automatically multiplication..im just lost
The funky S-shaped symbol is an elongated S called an integral sign. It means a continuous sum. The dx refers to a dinky change in x, that is infinitesimally thin.
The way that x^2 turned into x^3, comes from the power rule. In general, when you do the reverse process called differentiation, an expression in the form of k*x^n, turns into n*k*x^(n - 1). In other words, you leave the original coefficient (k) alone, and have the existing exponent (n) join the coefficient. Then you reduce the exponent by 1, so that it is now (n - 1). There are limit proofs of this rule you can look up, but in general, it comes from the binomial theorem of expanding (x - h)^n to show this from first principles of how we define the derivative.
To reverse this process for integration (which the fundamental theorem of Calculus proves is connected to derivatives) we reverse the formula, and get k/(n + 1) * x^(n + 1). So leave the coefficient alone, increase the exponent, and have the new exponent join the coefficient down below. Do this for x^2, and we end up with 1/3*x^3. Plus an arbitrary constant if applicable, as we do for unbounded integrals in general.
What?!😵💫
How do you find the area of something thats not a function? If i were to draw a random shape could you find the area using calculus?
One way you could do it, is with Simpson's rule. This is a method that gives more computational efficiency than the standard Riemann Sums they teach you, when laying the groundwork for understanding integrals, in the prologue to calculus.
Simpson's rule constructs parabolas among each group of three data points, so that it samples a representative position, slope, and curvature, of the shape, that then varies throughout the shape's domain. The formula for Simpson's rule is set up so that you don't even need to think about parabolas to use it. This is what you'd do if you were given a shape and could measure data points to figure out what the curve is, but didn't know what mathematical function defined those points. One place you might see this, is the way CAD software estimates the volume of exotically shaped parts.

I think you have to have some prior knowledge of calculus for this to fully make sense.
I get that calculus is used to solve area problems.
I've not been exposed to calculus prior to this.
This didn't really help me understand it, beyond why calculus is used.

1. Calculus is also about derivatives...
2. Where are limits? They may be needed if you have not a perfect function from examples.
3. We only understood that calculus is about doing some integration to find area of shape.
Go watch a normal video, not that clickbait that will fool you
Meanwhile I'm wondering what is the purpose of the area of this curve 😅
