int(dx)/(cos x+cosec x)

Evaluate: int(1)/(cos x+csc x)dx

int(dx)/("cosec"x+cosx)=

If I=int (dx)/(secx + cosec x), then equals

int(dx)/(sec x+csc x)

int1/(sec x + cosec x) dx

int1/(sec x + cosec x) dx

int (dx)/(sec x + "cosec x")

int (dx)/(sec x + "cosec x")

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
