Thank you so much.  You do not understand how much this video and all of your others have helped me in AP Calculus.  I can honestly say i would fail without these videos.  THANK YOU FOR ALL YOU HAVE

I'm in 6th grade and was having trouble keeping up. Thanks for the video! It was a lifesaver

I'd like to know how you were fairly certain you could factor the quadratic rather than use the Quad Formula in this example but in your video 2 you say "I might be able to factor" but then you move on to the QF. What's the key to knowing---just a gut feeling based on years of experience?

can you make a video on this problem ?

" A body falling from a given height H hits an inclined plane in its path at a height h . As a result of this impact, the direction of the velocity of the body becomes horizontal. Find the value of h/H for which the body will take the maximum time to reach the ground."
