" 11.Evaluate: "int((3sin phi-2)cos phi)/(5-cos^(2)phi-4sin phi)d phi

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

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

(3 cos phi+cos 3 phi)/(3 sin phi-sin 3 phi)=

Prove: (sin phi - cos phi) ^(2) =1 - sin 2 phi.

phi is an acute angle such that tan phi=(2)/(3) then evaluate ((1+tan phi)/(sin phi+cos phi))*((1-cot phi)/(sec phi+csc phi ))

Evaluate the integrals int_0^(pi/2) sqrt(sin phi)cos^5 phid phi
