`int (1-cos 2x)/2 dx`

int 2/(1-cos 2x) dx

int 2/(1+cos 2x) dx

int(1)/(1-cos 2x) dx

Choose the correct answer of the given question int 2/(1-cos2x) dx =

int cos (2x +1) dx

int(1-cos^2x)/(sin^2x)dx=?

(i) int(1)/((1+cos2x))dx , (ii) int (1)/((1-cos2x)) dx

Evaluate (i) int_0^(pi//4) sin x cos x dx (ii) int_0^(pi//2) (1 + cos x)^(1//2) dx (iii) int_0^(pi//2) (1 + sin x)^(1//2) dx (iv) int_0^(pi//4) (1 -cos 2x)^(1//2)dx

int sqrt(1+ cos 2x) dx = ?

int sinx/(1-cos^2x)dx
