Parametric Curves - Finding Second Derivatives

[patrickjmt]

sweet! now if only it worked the same way for the students in my class... maybe i should turn on my videos instead of teaching!
good luck on the exam!!

This video was more helpful than my teacher talking for two hours about this. Really appreciate your help! Thanks!

I didn't know anything in my calc class that I've been taking for a month... my highest quiz has been a 70 something but my second highest is a 30... You have changed EVERYTHING.... I'm trying to become a mechanical engineer and so far I'm blown away by the amount of knowledge i've gained over the last few hours of watching your vids... I appreciate this so much man THANK seriously your a life saver..

Thank you so much Patrick, Dr. Patrick, Awesome Patrick. I am a Computer Engineering student and I have trouble learning math but you have helped me on my Calculus courses since Cal 1. I am now in my first week of Cal 3 and I will be looking at all your videos for help since at my school the classrooms are huge and not much one on one is possible. I appreciate all your help. Wish me luck man.

Salute to you and all those taking maths tutorials online ... It was very helpful

My book doesn't explain the intuition behind this at all, so I don't get why this formula ends up the way it is. how does d/dx(dy/dt / dx/dt) end up with dx/dt in the denominator? how does d/dx(dx/dt) = dx/dt?

@mikethered123 thanks for the comment!! it is very useful!

Why aren't you my professor? You make it look so easy and you explain each step and why you did it very clear. Thank you so much !!!

I know this video is 12 years old, but you are getting me through College Calc II as a freshman. Thank you Patrick :)

My calc 2 grade went from D to a B thanks so much

[rivalsdynamic]

thanks man i was now able to understand the whole concept bro literally you was doing solutions and i was doing everything correctly before u and at last i got to know that how to use that formula for second order derivative thanks man

[drakesterX]

This helped A TON!! Thank you so much for this tutorial!!

[KLDozer]

Economics major here, I struggle with calculus 2 this whole semester, 4hrs away from my final and i finally get the concept. I feel my tuition should go to you instead of my nonEnglish speaking TA n Prof

[lolrandom]

i would probably have failed calc 2 without these videos. Thanks a lot.

[gracenkem]

You click your tongue an awful lot, but you're a great teacher/tutor.

Much appreciated! :)
