You got a begineer video explaining what paramatization even is? Im in calc and they getting us to do these questions relationed to finding a line and a slope using t as a parameter. I've literally never learnt anything about parametric or paramatization before so yeah.
Yup, personally he helped me get through Precalc, Mechanics, Diff. Calc, and Integral Calc.; I will probably use his videos to teach myself for Electromagnetics and Vector Calc./Linear Algebra as well
In other lectures there is usually a lot of assumed knowledge involved. Which makes sense since this is not low level math, but for someone like me who struggles with adding fractions but is in precalc your videos somehow make it all make sense. It is like MAGIC. Your videos almost always answer every question I have lingering before I have to google or mathway. I am so excited to be understanding math for the first time in my life, its EUPHORIC. Thank you times a million, yeehaw
you struggle with adding fractions in pre-calc? hoe fdid you get this far lol that's crazy. Also there is in now way THIS is in pre-calc, is that what you're saying?
If you tell yourself you're going to inevitably fail an exam it's because you either didn't study enough or you don't have confidence in yourself, gotta believe in yourself and put in the work bro
@@PepsimVideos true I mean studies(from my psych class, sorry no source yet) show, if you say your going to fail, you will be at least 2* more likely to fail
Learned everything I needed to know about parametric curves within the first 10 minutes. My professor has been teaching this subject for a week now and we had a quiz on it, the class average was about a 70ish percent, I got a 94 and before I watched this video I barely know anything about this, had I not watched this as I was frantically studying before the quiz, I would have guaranteed failed it. Thank you so much.
Bro, you are actually the smartest person alive. Wtf. You have so many videos on so many different topics and they are all taught so well. I wish you were my teacher lol
Professor Organic Chemistry Tutor, thank you for a positive introduction to Parametric Equations. This is a well-known process of eliminating t in order to get y in terms of x. This material is introduced again in Calculus II and Calculus III. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
my online coursework is doing a crap job at teaching these things. i learn by understanding what it is and why first not a series of IF/THEN statements to memorize... sucks because conceptually i thought this would be easy to learn. but the programs teaching methodology is so inefficient and backward im often having to do what i did BEFORE coming to school which was to scrape together an understanding through free content. maybe this online format just isnt for me, maybe its just a bad version being used. it would be alright if it was more thorough but personally, Im thinking just need a professor i can get clarification from as concepts are being introduced. I wish you all luck with your coursework friend!
You’ve helped me through Calc, Calc2, Calc3, Calc4, Calc5, Calc6, and Calc7!!! Not even gonna mention DE 1-12!!! Thank you sooooo much I appreciate it ❤️
My calc teacher has just been uploading videos for this semester because covid, but I just found out about this channel from a friend and wow this is so much better. Hopefully I can pass this next exam
Great video, thanks! This is so helpful, sir. A little thought on the problem around 25:00: x=2^t, y=2^-t. To eliminate the t, we can just say xy=1, and hence, y=1/x. 2^t*2^-t=2^(t-t)=1. So, xy becomes 1. Since both 2^t and 2^-t are not equal to zero, we can divide xy by x, and we get y=1/x.
You need to start by defining what a parametric equation IS, why it IS neccessary(if it is so), why and how it came into being. That is an excellent pedagogic method.
"This PreCalculus video", Yeah you better know it forwards and back because in Calculus 2 you will be expected to already know this. Many students are underprepared. PreCalc, can only focus on so much. So some students are here studying it in PreCalc, another majority in Calc 2 wondering where the heck it came from :D
Helpful video, but I wish you would've done some examples with cos and sin where the numeral was on the t instead of in front of the trig variable (ex. cos(1/2(t)). Not really sure how to deal with this.
There's often noises in the background of his videos like ambulances, cars, motorcycles, sometimes even birds chirping! I know this because I've watched like over 600 videos of his. He's a good tutor.
I have a question.... at 2:35-2:44, they said t=0, 1, 2, 3, and 4. wouldn't that be the x values? Isn't t=-2,-1,0,1 and 2? And besides, if t=[0,4] then wouldn't that cross the domain or something?
Samira Tamma yeah he made a mistake. The t value correspond to the coordinates and you choose the direction of lowest to highest from the values where t are
2:35 hi can anyone explain to me y he wrote (in green) the r values starting from 0? Because I thought that the points of y he used to plot the graph was from -2 to 2?
He labeled them in order from top to bottom starting at 0 not based on what t actually is , your correct tho, the reason he’s labeling them like that is because he’s tryna show which way the arrows are going but it just makes it more confusing in my opinion you don’t need to label yours when you do them 😅.
maybe a little late but that is because you are trying to get rid of the sin and cos so you set the parametric equations equal to sin and equal to cos then you can use the identity to solve to find the x and y equation.
Thankyou sir.but Im confused with the t values labelled on the graph first example. How do we go from t=(-2 to 2) to t=(0,1,2,3,4) labelled on the graph.

At 2:48 on the graph, isn't it t=-2 for the leftmost point? rather than t=0?
Riiight? Thank you. I'm not crazy.
I think his brain was on autopilot mode and he just started at zero instead of -2
i also thought that
Sorry. I know I'm late but it should be t = -1 at point (1,1), t = 0 at point (2,0) and so on???
@@pridetrooperjiren548 yes, that's what they mean

I had a test where I had to convert a parametric equation to a rectangular and I didn’t know how. I swear to god I guessed and did exactly this.
Thank You 😁 I passed my exams in Calculus
How you going to tell me to pause and do it but then change the whole question 3 seconds after?
lol that's painful
be happy that he makes videos haha
I felt this pain
i felt this
I was really struggling to find a proper lecture on this topic!! Thank you so much !! It was really really helpful!

John Landon Miller this isn't his first video on the subject
Almost everyone in my university uses your videos
I love you man 😂❤🫡😭May all the wonderful things in the world gravitate to you ❤😭you are literally saving my life right now 😢
at 27:57, there was a simpler way to get y=1/x. like y=2^-t the it also equals to y=1/2^t right, then we replace 2^t with x. we got the y=1/x
bless your soul you have saved me too many times

The organic chemistry tutor guys!
i literally learn more in your videos than in my college
YAAASSSSSSSSSSSSSS. YOU'RE LITERALLY MY SAVIOR
I believe there is a mistake at 2:54, because t-values were -2, -1, 0, 1 and 2. On the graph he started with values 0,1,2,3,4. Am I wrong?
You are right, but it doesn't affect how the graph looks and the directionality. The t values should be from -2 to 2 though
gonna take my calc 2 final tomorrow, wish me luck guys
I am here again. Thank you for this video.
at 5:55 t= 4 not 2 on the uppermost coordinate

was told sequences/series was hardest part of calc 2 but wtf is this, way harder than any sequence/series problem lol
RIGHT- everyone was like “ohhh taylor series is the hardest thing you’ll ever do!1!!1” yet no one talks about this shit which is worse 😭
lol 13:23 he changes x = 3sint to x = 2sint. Loved the video btw it helped a lot.
nvm i got to where he fixed it lol
Bro I fuckin love this channel. Professors can't teach for shit. (Sometimes)
Bro you're a god.
So do you eliminate the parameters only when you have no restrictions?
I wish you went more in depth with problems like x = sec t, y = cot t. Things that aren't already in sin and cos

Why not just do log base 2 on both sides right from the start? Why use the natural log then use change of base formula?
If equation is given a we have to find parameterization like _2≤0≤2
In the x=2^t problem, couldn't we just multiply x and y to get xy=1 and then graph it? Looks much simpler to me....

Hello.
May I ask why, specifically, the trig ID was used, at 11:40? I am lost at this point.
maybe a little late but that is because you are trying to get rid of the sin and cos so you set the parametric equations equal to sin and equal to cos then you can use the identity to solve to find the x and y equation.
Thankyou sir.but Im confused with the t values labelled on the graph first example. How do we go from t=(-2 to 2) to t=(0,1,2,3,4) labelled on the graph.
what about double angles how to do that x= -7cos2t, y=-7sin 2t 0
Put 2t = m ( or any other variable of your choice ecept x nd y)
So, as 0
13:06 x=3sin(t) is changed to x=2sin(t)
nvm he caught it, i should have just watched a little bit further
Do you have one where you do a question like y=sint-t x=cost
After eliminating t, we get
Y= [ √(1 - x^2) ] - cos inverse x
