(9(3sin phi-2)cos theta)/(5-cos^(2)phi-4sin phi)d theta

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

(sin theta-sin phi)^(2)+(cos theta-cos phi)^(2)=4sin^(2)(theta-phi)/(2)
