" 2.If "tan theta=(x sin phi)/(1-x cos phi)" and "tan phi=(y sin theta)/(1-y cos theta)," then "(x)/(y)" is equal to "

If tan theta=(x sin phi)/(1-x cos phi) and tan phi=(y sin theta)/(1-y cos theta) then the value of (x)/(y) is

If tan theta = (x without phi) / (1-x cos phi) and tan phi = (y without theta) / (1-y cos theta) then (x) / (y) = (A) (without phi) / (without theta) (B) (without theta) / (without phi) (C) (without phi) / (1-cos theta) (D) (without theta) / (1-cos phi)

If tan theta = (xsin phi)/(1-xcos phi) and tan phi = (y sin theta)/(1-y cos theta) show that x sin phi = y sin theta

If sin theta sin phi - cos theta cos phi+1 =0 then the value of 1+ cot theta tan phi is-

If cos(theta+phi)=m cos(theta-phi) then tan theta is equal to

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

If " " tan theta = 1/7 " and " tan phi = 1/3 " show that", cos 2 theta = sin 4phi

"If" (a cos theta sec phi - x)/(a sin (theta + phi)) = (y - b sin theta sec phi)/(b cos (theta + phi)) = tan phi, "show that," x^(2)/a^(2) + y^(2)/b^(2) = 1.

If 3 tan theta tan phi=1, then (cos (theta-phi))/(cos (theta+phi)) is

If 3 tan theta tan phi=1, then (cos (theta-phi))/(cos (theta+phi)) is
