I am a calc 2 student. And I stopped going to lectures cause I have no idea what that old fucken professor is talking about. Instead I go to the library and I look at your videos and try to understand the topic myself.

Thanks a lot god bless you

Much respect to the creator of these videos.

I learned more from this 10 min video than my past 2 lectures that are over 2 hours long... thanks college!

Seriously you are the BEST!! I love how you explain every little step, even if it is a small addition or subtraction step. And thank you for not having a condescending tone!!!!

Made a youtube account just so I can thank you for these videos. Thank you so much!

This is literally the question I have been stuck on for half an hour god bless you Patrick still saving uni kids 11 years later

I can't explain to you how great it is that you make good quality videos. I've been going over calculus 2 material since I am currently in that class. The way you explain is very straightforward and is helpful to watch right before an exam or starting my homework online.

Your videos are quick and concise, very easy to watch..and not too tedious. I happen to have a very good calc teacher, and adding the fact that I watch your video as review, this is making my math become extremely potent. Thanks Patrick.

@ace0415 for these type, you often end up factoring and doing some sort of u-sub. in general though, it could be quite difficult. but in a textbook, these problems are set up to work out

My Calculus 2 professor faces the board and speaks in very broken English. You have clarified in 10 minutes what he spent 2 hours twisting into an indiscernible mess. Thank you.

I freaking love you, took me a while with my studying to figure out wtf the book was talking about and you just made it

[patrickjmt]

well, that is a circle of radius r, so you can use C = 2pi(r) (circumference formula) ... in this case, divide by 2 cause you only get the top half, so answer should be (pi)*(r)

Thank you so much for posting. Yesterday in class when the AP calc teacher went over this stuff, I had no idea what he was talking about. I didn't even know what arc length meant! Now, after watching this, the concept of it seems really simple and do-able. THANK YOU!!

[patrickjmt]

glad you like my videos :) spread the word!

I have a calculus exam tomorrow and this will probably be on the test...  really love how easy these videos are to understand because I simply cannot learn in my lecture. My professor basically turns her back to the class and talks to the whiteboard the entire time, but this is so much better for me! Thank you so much, hopefully I do well on my test tomorrow!

THANK YOU - I do IB and you have actually saved my maths internal assessment - I was trying to calculate the arcs of a basketball trajectory and I used parametric equations but it got weird because I had higher release angles getting shorter arcs - you're a legend, thank you

[ShankGoof]

Thanks man! i missed class the day prof went over arc length. This has been a life saver, yet again! thanks!

[paretcl]

You sir are the reason im passing Calc 2. Thnx soo much!!!!

[mrreilly]

Thanks a million for this video! I had a sub for my calc 1 class for this topic and he was awful. He taught it in an hours time with the proof and one example and I didn't understand a thing. He was basically a talking text book. Ten minutes of your video made this so simple to understand! Thanks!
