" If "x sin phi=x sin(2 theta+phi)+th tan3-T(x+y)cot(theta+phi)

If y sin phi=x sin(2 theta+phi) show that (x+y)cot(theta+phi)=(y-x)cot theta

If y sinphi = x sin (2theta + phi) show that (x + y) cot (theta + phi) = (y-x) cot theta .

If y sinphi = x sin (2theta + phi) show that (x + y) cot (theta + phi) = (y-x) cot theta .

If sin theta = k sin (theta + phi),"show that", tan(theta + phi) = (sin phi)/(cos phi -k).

If sin theta=5sin(theta+phi) then tan(theta+phi)=

If sintheta=5sin(theta+phi) then tan(theta+phi)=

If sin theta=k sin(theta+phi), show that tan(theta+phi)=(sin phi)/(cos phi-k)

If : sin (theta + phi) = 2 sin (theta - phi), "then" : tan theta = A) tan phi B) 2 tan phi C) 3 tan phi D) 4 tan phi

cos 2theta cos 2phi + sin^(2) (theta - phi ) - sin^(2) ( theta + phi) is equal to
