Question

f(x)=log(tan e) find f'(x)

Answer 1

Given,

f(x)= log(tan e)

Differentiating both sides with respect to x

f'(x) = d(log(tane))/dx

f'(x) = 0

Alternatively, F(x) is not a function of x .it is constant. Hence its differentiation will be zero

Answer 2

Heya

______________________________

If your questions is f(x) = log ( tan e )

then. F'(x) = 0

But if your question is like this

f(x) = log ( Tan x )

Then

F'(x ) = Sec² x / Tan x
