`∫ Sec^2x * Cosec^2x dx`

int sec^(2) x cosec^(2) x dx

int sec^(4)x cosec^(2)x dx is equal to

Consider the following equations (i) cosec^2 x + sec^2 x = cosec^2 x sec^2 x (ii) sec^2 x + tan^2 x = secx tan^2 x (iii) cosec^2 x+ tan^2x = cot^2x + sec^2x Which of the above equations are correct ?

int cotx cosec^2x dx

(i) int e^x sec^2 (e^x) dx (ii) int e^x cosec^2 (e^x) dx

int (sec^(2)x)/(cosec^(2)x) dx

Evaluate: (i) int(5x^(2) + 2x^(-5) - 7x + 1/(sqrt(x)) +5/x) dx (ii) int(3sinx - 4 cosx + 5 sec^(2) x - 2cosec^(2)x) dx (iii) int(1-x)(2+3x)(5-4x)dx (iv) int((3x^(4) - 5x^(3) + 4x^(2) -x + 2)/(x^(3)))dx , (v) int(x^(2) + 1/(x^(2)))^(3) dx

Integrate : int ( sec^2x dx )/ ( cosec^2x )

int (sec^4x.cosec"^2x) dx=

tan^2x + cot^2 x +2=sec^2 x cosec^2 x
