With the limit being the limit for h goes to 0. Finding the derivative of a function is called differentiation. Basically, what you do is calculate the slope of the line that goes through f at the points x and x+h. Because we take the limit for h to 0, these points will lie infinitesimally close together; and therefore, it is the slope of the function in the point x.

So, first we will take the derivative of 1/sinx, then we will take the derivative of cosx/sinx, that is, cotx. The function sin (x)cos (x) is one of the easiest functions to integrate. All you need to do is to use a simple substitution u = sin (x), i.e. frac {du} {dx} = cos (x), or dx = du/cos (x), which leads to It is worth mentioning that the C in the equality above is not the same C as in our original expression. As the derivative of a constant is 0, we deduce that the derivative of one is zero. There were.
