`(d(cosx)^(cos x))/(dx)`

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

int (cosx)/(cos 3x)dx

If y=(cos x)^((cosx)^((cos x )...oo)) then prove that dy/dx=(y^2 tan x)/(y log (cosx)-1).

Differentiate the following w.r.t. x : x^(cosx)+(cosx)^(x)

"If "y=x^(cos)+(cosx)^(x)", prove that "(dy)/(dx)=x^(cosx).{(cosx)/(x)-(sinx)logx}+(cosx)^(x)[(log cos x)-x tan x].

int(sinx)/(sin(x-a))dx-int(cosx)/(cos(x-a))dx=

int (cos2x)/(cosx) dx=

int(cosx)/(sqrt(cos2x))dx=

Differentiate the following w.r.t. x : x^(cosx)+(cosx)^(sinx)

Evaluate int(cosx-cos2 x)/(1-cos x) dx
