10I=int sin^(4)x

int sin^(4)x*dx

If I_(1)=int sin^(-1)x dx and I_(2)=int sin^(-1) sqrt(1-x^(2)) dx then -

Method of integration by parts : I_(1)=int sin^(-1)x dx and I_(2)= int sin^(-1) sqrt(1-x^(2))dx then.....

obtain reducation formula for I_(n)=int sin^(4)dx Hence evaluate int sin^(4)xdx

I= int sin^(2) 3x dx .

I=int sin^(-1)(2x)dx

Evaluate: (i) int sin^(3)x cos^(5)xdx (ii) int(1)/(sin^(4)x cos^(2)x)dx

(i) int sin^(3)x cos^(4)xdx

int sin2x sin^(4)xdx

Evaluate: (i) sin^(4)x cos^(3)xdx (ii) int sin^(5)xdx
