Not sure I understand basic calculus...
February 15, 2019 at 12:00 pm
I've began to study calculus on the university. I thought I understood it back in high school, but, once I got slightly deeper into it, it turned out I don't.
Here is my question, if the derivative of the inverse function is the reciprocal of the derivative of the function, and the derivative of the arctan function is 1/(1+x*x), how come the derivative of the tangent isn't 1+x*x but is instead 1/(cos(x)*cos(x))?

Now send grandizer a lot of hookers and blow for the help he gave you. Or a rep point if he isn't into it.

Just remember that for every epsilon, there is a delta. Kind of like for every scraggly horse, there is a scraggly bush. It's cleverly disguised math porn.
