int((x cos alpha+1))/((x^(2)+2x cos alpha+1)^(3))dx

If int(x cos alpha+1)/((x^(2)+2x cos alpha+1)^((3)/(2)))dx=(f(x))/(sqrt(g(x)))+c then find f(x)

If int ((x cos alpha+1)dx)/((x^(2)+2x cos alpha+1)^(3//2))=(f(x))/(sqrt(x^(2)+2x cos alpha+ 1))+c then f(x)=

int ((cos 2x - cos 2 alpha))/((cosx -cos alpha)) dx = ?

int(cos2x-cos2 alpha)/(cos x-cos alpha)dx

(cos2 x - cos2 alpha)/(cos x - cos alpha)

Prove : int ( cos 2x - cos 2 alpha )/(cos x - cos alpha ) dx = 2(x cos alpha + sin x) +c

Evaluate: int(cos2x-cos2 alpha)/(cos x-cos alpha)dx

Evaluate: int(cos2x-cos2 alpha)/(cos x-cos alpha)dx

If cos y=x cos(alpha-y) then (1+x^(2)-2x cos alpha)*(dy)/(dx) is (A) sin alpha (B) -sin alpha (C) cos alpha (D) -cos alpha

Evaluate the integrals int(cos2x - cos2alpha)/(cosx - cos alpha) dx
