int e^(x)cos2xdx

int e^(x) cos xdx

int(1+x)cos2xdx

int e^(x)cos^(2)xdx

int e^(x)cos^(2)xdx

Show that, int_(-(pi)/(2))^((pi)/(2))cos^(5)xdx=2int_(0)^((pi)/(2))cos^(5)xdx and find the value of int_(-(pi)/(2))^((pi)/(2))cos^(5)xdx .

Prove that, int_(-(pi)/(2))^((pi)/(2))cos^(3)xdx=2int_(0)^((pi)/(2))cos^(3)xdx , hence, find the value of int_(-(pi)/(2))^((pi)/(2))cos^(3)xdx

int e^(-x)cos2x cos4xdx

int(e^x+1)^2e^xdx
