" If "sin theta=15sin(theta+phi)" then shav that "tan(theta+varphi)=(sin varphi)/(cos phi-k)

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

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

If 3 tan theta tan phi=1 , then prove that 2 cos (theta+varphi)=cos (theta-varphi) .

If 3 tan theta tan phi=1 , then prove that 2 cos (theta+varphi)=cos (theta-varphi) .

If sin(theta+phi)=n sin(theta-phi), then the value of (tan theta)/(tan phi) is equal to

If (a-b)sin (theta+phi)=(a+b)sin(theta-phi) and a tan. (theta)/(2)-b tan.(phi)/(2)=c , then

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

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
