Unrelated to the video, but I just wanted to say thank you for the Linear Algebra series, it helped so much! If you could do a whole series on ODE's, you would literally be the greatest to ever do it. Please and thank you :)
This subject is hard for me because the word problems are not realistic. For example, how can 1 side of a ladder move faster than the other side. In the real world universe in which we all live in, how can a ladder increase its distance from a wall at 1ft/s while falling towards the ground at 3/4ft/s. The only way is to increase the length of the hypotenuse (ladder) which the derivative is not taking into account.
