This is where we start to see that calculus can be a better and quicker way to compute certain things - instead of calculating the vertex of the parabola to find maximum height, we can use the derivative to find where the slope of the tangent equals zero.
I missed this day in class and the textbook was not helping...you just helped me navigate my homework problems, thank you so much! You are a great teacher.
Thank you thank you for this channel 😍 sending virtual hugs! I thought I don't have the chance to ever understand physics. But thank u for this channel. More vids in the future 😊 godbless you
Professor Organic Chemistry Tutor, thank you for an awesome explanation of the Average and Instantaneous Velocity in Calculus. Thís is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
you deserve to be thank mr you are really great better most of this so called professors in the universities thanks a lot... upload this kind of videos when calculating 3 dimensional vectors
The part (e) of the question where the quadratic equation was used, you answer was 21.9 s and I calculated twice and I got 2.19 s. So , when that calculation of the speed of the ball going to the ground the my answer was different 76.6 m/s. But other than that I love your videos and have been following you for awhile. Thank you.
at 00:36 i wanted to ask how doesn't move to the right? if it doesn't move to the right then it would go up and land on the same position it was projected from which is on the building not the ground?
For d) around 10:53, when it says "average velocity", is it possible to plug in t = 4, t = 5, t = 6 to v (t) and then find the average using (v(4) + v(5) + v(6) )/ 3? The v(t) can be found by differentiating the given s(t) equation so I was wondering what will be the difference between your method and mine.
Yep! You can definitely use that method to find the average velocity in this scenario. You would still get 49. I would say the only difference between your method and the method he uses in the video is that his method might be a bit faster. However, if you like using your method better, then by all means use it. Hope that helps!
I think that's because the general ecuation for the Y axis is Yf = Yo + VyoT + 1/2*a*t2, 'a' being the Y acceleration. Here, the acceleration is -g, so it would be 1/2 * -g * t2, which is the same as -1/2 * g * t2. Hope that helps, and sorry for my bad english :D
Find the derivative, and plug in for f(x). For example, if you are given f(x)=2x^2 at x=3 the derivative would be 4x, then you would plug in 3 --4(3)-- making the answer 12.
bro my Approach on question (d) since the functon was of (time, displacement) => (t,x) and remembering that Vav= Δx/Δt => Vav=(x2-x1)/(t2-t1) where x1=6, x2=5.1, t1=4, t2=4 as of result my Vav= (5.1-6)/(4.9-4) =-1m/s How is mine differrent from yours 😢😢
because the question ask when does ball hit the ground. The ball hit ground when the height is 0 so you set position function to zero and try to factor. He use quadratic formula to factor it to find the time it hits the ground.
using a acceleration function you can. If you take the integral of the acceleration function with respect to time you get the velocity function with respect to time

This genuinely was more concise and helpful than any teacher that I've went to, thank u
2 sections of 1 chapter that takes hours to read crammed in a few minutes. This I needed. Btw I like ur accent
You could hear the confidence when he said "and the little questions that go with it that type of problem" good stuff man, here from South Africa
This man has taught me more in 20 min then me prof has all semester
You're actually my dad.
That's crazy, my m8
Wut.!!

it's all so simple now this man is actually a legend
The best teacher you're not just teacher you're pro teacher God bless you big respect
you are the best math teacher in you tube and I claim it as a maths teacher of 30 years :))))
i don't how to thank you enough
the surprising part is you are good at everything thank you sooo much
i wouldnt pass my calc class without you
This is physics though
Thanks alot, this is so super helpful to the community, hugest appreciation ❤
Thanks so much! I learn more from your videos than any Physics class! Keep it up

Aye man thx. It's my first day of college today and I can learn from the book. Thx man, your vid saved my HW, I understand it 🔥🔥🔥

This man is the GOAT
I have learned more from these youtube videos than 4 semesters of crappy professors.
at 00:36 i wanted to ask how doesn't move to the right? if it doesn't move to the right then it would go up and land on the same position it was projected from which is on the building not the ground?
That was a long problem but I feel like I learned a lot thank you.
I was wondering why is the derivative used when calculating velocity?
Bc the derivative is the rate of change which is also velocity
@@MoneyBytesAI thank you
Ackkk your voice is really good:
thanks for teaching 🌹
I like your teaching method
For question g, can we use the v = u +at
v=0m/s
u=98m/s
a=9.8m/s^2
0=98 + -9.8t
t = 10
You're the G.O.A.T!
For d) around 10:53, when it says "average velocity", is it possible to plug in t = 4, t = 5, t = 6 to v (t) and then find the average using (v(4) + v(5) + v(6) )/ 3?

hi, great video. I just want to know how you determined that the units was in meters per second. im a little confused on that part.
This guy deserve novel prize
Thanks❤
where can I find more sample problems like this? tried and cant
wtf im confused you plugged in 9.8(0) at 2:04 then at 3:49 the derivative turns to 98??
it makes no sense why did it change first it was 9.8t then it was 98t ? wtf
RIGHT LIKE WHAT HAPPENED
Hey wait. At 4:41 Why did you use
Yf = Yo + VyoT - 1/2gt2 instead of
Yf = Yo + VyoT + 1/2gt2
I think that's because the general ecuation for the Y axis is
Yf = Yo + VyoT + 1/2*a*t2, 'a' being the Y acceleration.
Here, the acceleration is -g, so it would be 1/2 * -g * t2, which is the same as -1/2 * g * t2.
Hope that helps, and sorry for my bad english :D
Mine just asks what is the instantaneous velocity ?? How do I solve??
Find the derivative, and plug in for f(x).
For example, if you are given f(x)=2x^2 at x=3
the derivative would be 4x, then you would plug in 3 --4(3)--
making the answer 12.

this man should have his own online unaversity
OK but what is the formula for instantaneous velocity? And what exactly does the limit mean in terms of that formula? I'm 100% lost
13:38 how would i know when to use quadratic formula?
That really depends on you. If you find splitting the middle term tough for some equations then you can use this instead. That's really up to you.
when you get a decimal or square roots in the equation
what grade level is this like in what grade do you get these problems
who else studying this 1 hr before the test.
good physics bro
But which one do you know best of the three
bro
my Approach on question (d)
since the functon was of (time, displacement) => (t,x) and remembering that Vav= Δx/Δt => Vav=(x2-x1)/(t2-t1) where x1=6, x2=5.1, t1=4, t2=4
as of result
my Vav= (5.1-6)/(4.9-4) =-1m/s
How is mine differrent from yours 😢😢
at 4:04 he leaves off the +200, why is that?
Coz derivative of a constant value is zero my brother ❤
ty sir
Pardon my idiocy, where did 21.87 come from for part F?
The previous part d
Confused me too until I realized that 21.9 was simply his rounded answer but he used the unrounded answer of 21.87 for the function.
put the video on 1.5 speed, you're welcome
where does -9.8 come from?
What is your native place
why did he not include 200 in solving instantaneous velocity?
why is this one so quiet? I thought it was going through my headphones
why do we use quadratic on question number E?
because the question ask when does ball hit the ground. The ball hit ground when the height is 0 so you set position function to zero and try to factor. He use quadratic formula to factor it to find the time it hits the ground.
Wewe unajua kila kitu😂
It would be nice to see your handsome face in one of the videos.
weird
why is t 0 at A.
Part E t = 7,45sec
ho its going to 21.9 but the answer in calculator is not the same of that?
in question e
please answer
i love you
ily
well im about to fail this test.
Fr 😭😭
Got a 93. Pissed cause my teacher shorted me points for nonsense.

How can I find the velocity using integrals?
using a acceleration function you can. If you take the integral of the acceleration function with respect to time you get the velocity function with respect to time
Very complicated
It's not
Bcus u didn't liste'
I'm 13
I am soooo confused 😢😢
7th graders?
😍😚
I honestly think he's not good at teaching and hate having to watch his videos, math minded people are in general very bad at teaching math.
This guy is nasally enough as it is. Now your gonna tell me hes speaking english but his words dot make sense. Is it cause I'm not a virgin?
Yes
Wut..!!?
