" 25."int(cot x)/((cosec x-cot x))dx=?

int (dx)/(cosec 4x-cot 4x)

int(1)/(csc x-cot x)dx=

int cosecx(cosec x + cot x) dx = ?

int (dx)/(sqrt(cosec 4x - cot 4x))

Evaluate: ( i int(cos x)/(1-cos x)dx or int(cot x)/(csc x-cot x)dx (ii) int(cos^(2)x-sin^(2)x)/(sqrt(1+cos4x))dx

Find: int cosec x (cosecx-cot x) dx

int(cot^(2)x)/((cosec^(2)x+cosec x))dx=

Evaluate the follow integrals: int (cosec x dx)/(log (cosec x- cot x))

int(1)/(sqrt(cosec^(2)x+cot^(2)x))dx=

int(1)/(sqrt(cosec^(2)x+cot^(2)x))dx=
