int_(0)^((pi)/(4))sec^(3)xdx

int_(0)^((pi)/(4))sec^(4)xdx

int_(0)^((pi)/(2))(sec^(3)xdx)/(sec^(3)x+"cosec"^(3)x)

Evaluate :int_(0)^((pi)/(4))sec xdx

Show that, int_(0)^(pi)sin^(3)xdx=2int_(0)^((pi)/(2))sin^(3)xdx and hence, find the value of int_(0)^(pi)sin^(3)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_(0)^((pi)/(4))cos^(2)xdx

int_(0)^((pi)/(2))(sec^(2)xdx)/((sec x+tan x)^(n))

int_(0)^((pi)/(2))sin^(3)xdx

" 2.Evaluate "int_(0)^( pi/4)sec^(2)xdx

Show that, int_(0)^(pi)sin^(4)xdx=2int_(0)^((pi)/(2))sin^(4)xdx , hence, find the value of int_(0)^(pi)sin^(4)xdx .
