int sin^(3)(2x+1)dx

show that (a) int_(0) ^(2pi) sin ^(3) x dx = 0 , (b) int_(-1)^(1) e^(-x^(2)) dx = 2 int_(0)^(1) e^(-x^(2)) dx

int (1)/(sin^(2)2x )dx

int (1)/(sin^(2)2x )dx

Evaluate :int e^(2x)*sin(3x+1)dx

Evaluate: int e^(2x)sin(3x+1)dx

Evaluate: int_(0)^(1//2) (sin^(-1)x)/((1-x^(2))^(3//2)) dx
