" 32."(cos x)/(1-cos x)" or "(cot x)/(cosec x-cot 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

log("cosec x"-cot x)

cot^(-1)("cosec x"+cotx)

Prove that (1+ cos x)/(1-cos x) = "(cosec x + cot x)^(2)

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

csc x=1+cot x

sqrt(1+2cot x(cos ecx+cot x))dx=

int (cot x)/((cosec x - cot x)) dx = ?

int(1)/(cos x . cot x ) dx

int(1)/(cos x . cot x ) dx
