What is the derivative of #x^(tan x)#? Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos(x) and y=tan(x) 1 Answer Eddie Jun 26, 2016 # y' = x^(tan x)(sec^2 x ln x + tan x/x)# Explanation: #y = x^(tan x)# #ln y = ln x^(tan x) = tanx ln x# #1/y y' =( tanx ln x)'# #1/y y' = sec^2 x ln x + tan x (1/x)# by the product rule # y' = y(sec^2 x ln x + tan x (1/x))# # y' = x^(tan x)(sec^2 x ln x + tan x/x)# Answer link Related questions What is the derivative of #y=cos(x)# ?
