int(2sin2 phi-cos phi)/(6-cos^(2)phi-4sin phi)d phi

Find int( (3 sin phi-2) cosphi)/(5-cos ^2 phi-4 sin phi) d phi

int((3sin phi-2)cos phi)/(5-cos phi-4sin phi)d phi

int((3sin phi-2)backslash cos phi)/(5-cos^(2)phi-4sin phi)backslash d phi

show that , the value of tan ^(-1) ( (x cos phi )/(1- x sin phi ))- cot ^(-1) ""((cos phi )/( x - sin phi )) is independent of x and find its simplfied value .

The product of matrices A = [(cos^(2) theta, cos theta sin theta),(cos theta sin theta , sin^(2) theta)] and sin B = [(cos^(2)phi, cos phi sin phi),(cos phi sin phi, sin^(2) phi)] is a null matrix if theta - phi =

If theta-phi=pi/2, prove that, [(cos^2 theta,cos theta sin theta),(cos theta sin theta,sin^2 theta)] [(cos^2 phi,cos phi sin phi),(cos phi sin phi,sin^2 phi)]=0
