Derivative of arccos(x) with Implicit Differentiation | Calculus 1 Exercises

Показать описание
We find the derivative of arccos(x), sometimes written cos^-1(x), which is the inverse of cosine function. We find this derivative of arccosine using implicit differentiation, setting y=arccos(x), taking the cosine of both sides, then differentiating. We'll also need to use the Pythagorean identity and then we'll see an example of the derivative of arccosine with the chain rule. #calculus1 #apcalculus

couldn't this just simply be written as dy/dx= -cosec?
