Using logarithmic differentiation, find the derivative of
F(x) = (x^2+5)^(cot2x). Write the derivative in terms of x.
---
Rewrite::
y = (x^2+5)^(cot(2x))
----
Take the log of both sides::
let y = (cot(2x))*log(x^2+5)
------
Take the derivative of both sides::
y'/y = (cot(2x))(2x) + (x^2+5)(-2csc^2(2x))
-------
y' = [(x^2+5)^cot(2x)][cot(2x)(2x)-4(x^2+5)(csc^2(2x)]
