" 25."(x+cos x)(x-tan x)

Find the derivative of (x + cos x)(x - tan x)

Find the derivatives of the following : (x + cos x) (x- tan x) .

Find the derivative of (x + cos x) (x- tan x)

Find the derivative of (x + cos x)/(tan x) with respect to x

tan ^ (- 1) ((cos x) / (1-tan x))

Find the derivative of (i)(x^(5)-cos x)/(sin x) (ii) (x+cos x)/(tan x)

(tan x)/(1-cot x)-(cot x)/(1-tan x)=(sec x cos(x+1))

If int (f(x))/(log cos x) dx = - log(log cos x) + C , then f(x) is equal to a)tan x b) -sin x c) -cos x d) -tan x

The function (sin^(4)x+cos^(4)x)/(x+tan x) is

If x in(0,(pi)/(2))-{1,(pi)/(4)} then the expression (log_(cos x)(x)*log_(tan x)(x))/(log_(cos x)(x)+log_(tan x)(x)) simplifies to
