" 95) (iii) "int_(-(5)/(4))^((pi)/(4))x^(3)sin^(3)x

The value of int_(-(pi)/(4))^((pi)/(4)) x^(3) sin^(4) x dx is equal to -

int_((pi)/(4))^((3 pi)/(4))(x)/(1+sin x)dx

int_(-pi/4)^( pi/4)x^(3)sin^(2)xdx

int_((pi)/(4))^(3(pi)/(4))cos x*f(sin x)dx=

int_(-pi//4) ^(pi//4) x^(3) sin^(4) xdx=

int_(-pi//4) ^(pi//4) x^(3) sin^(4) xdx=

Evaluate: int_(-(pi)/(4))^((pi)/(4))(x^(9)-3x^(5)+7x^(3)-x+1)/(cos^(2)x)dx
