If `f(x) = co s x-cos^2 x + cos^3 x-....to oo` then `int f(x) dx` is equal to

If f (x) = cos x - cos ^(2) x + cos ^(3) x -... to oo, then int f (x) dx equals to :

If f(x) = cos x - cos^(2)x + cos^(3)x + …. to oo int f(x) dx =

If f(x)=cosx-cos^(2)x+cos^(3)x-…oo , then the value of int f(x) dx is equal to -

int cos x cos 2x cos 3x dx=

f(x) = min{2 sinx, 1- cos x, 1} then int_0^(pi)f(x) dx is equal to

If y = (cos x)^((cosx)^((cos x)...oo)), " then " dy/dx is equal to

If an antiderivative of f(x) is e^(x) and that of g(x) is cos x, then int f (x) cos x dx + int g(x) e^(x) dx is equal to :

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

int(cos3x-cos2x)/(cos x)dx
