If tan theta=(a)/(b) such that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))^(k) then k is ?

If tan theta=(a)/(b), prove that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))

If tan theta=(a)/(b), show that (a sin theta-b cos theta)/(a sin theta+b cos theta)=(a^(2)-b^(2))/(a^(2)+b^(2))

If : cot theta =(a)/(b), "then" : a *cos 2 theta +b * sin 2 theta= A) a^(2) +b^(2) B) a^(2) - b^(2) C)a D)b

If tan theta=(b)/(a) then a cos 2 theta+b sin 2 theta=

If (cos^(2) theta)/(a) = (sin^(2) theta)/(b) then (cos^(4) theta)/(a) + (sin^(4) theta)/(b) =

If tan theta=(a)/(b) then b cos2 theta+a sin2 theta=

Prove : (2 sin theta cos theta-cos theta)/(1-sin theta+sin^(2) theta-cos^(2) theta)=cot theta
