I would like to take a moment and thank the gentleman (Sal I believe) who took the time to make & upload these videos. I've been watching these videos since college algebra and a lot of these videos have helped me SO much. You are the best tutor ever. You are free, explain things extremely well, have a pleasing demeanor, and you're smart as hell. I've never struggled in ANY collegiate course. Hence, I never had to ask ANYONE for help. Then I found myself struggling a bit in Calculus and Pre Calculus, and I was either too proud or too arrogant to seek help. Thankfully, I found these videos and they pretty much help me through all the difficult math courses I'm taking. So, THANK YOU SAL. You are the FREAKIN best!!!

I think that the formula dy/dx=y(d(ln(y))/dx) should be taught and used widely, because it easily deals with taking the derivative of functions like x^x. It comes from the chain rule and the identity d(ln(x))/dx=1/x. It can be easily used to prove the product/quotient rule and power rule. I don't know who else has stumbled across this, but to me it seems like it should really be a fundamental part of calculus rather than an obscure little trick that no one has ever heard of.

Simple definition of implicit function: Multiple dependent variables of a single independent variable. For example if X is the single independant variable having 2 dependentvariables namely X and Y. Sort of opposite of partial functions with a single dependent and multiple independnt vaiables Besides awkward use of chain rule. So when finding say dY^2/dX by chain rule one should show all the steps. So initially we should write d Y^2/dY and not dY^2/dX. Then one can easily see that dY^2/dY = 2Y and dY^2 = 2Y*dY. Then dividing both sides with dX we finally get dY^2/dX =2Y*dY/dX. No need to use the confusing dg
