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 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 2theta + b cos 2theta =b

If tan theta =a/b , prove that a sin 2 theta+b cos 2 theta=b .

If tan theta = 1/b , then ( a sin theta - b cos theta )/( a sin theta + b cos theta) is

If tan theta=(a)/(b) , find the value of (a sin theta-b cos theta)/(asin theta+b cos theta)

If tan theta=(a)/(b), then (a sin theta+b cos theta)/(a sin theta-b cos theta) is equal to (a^(2)+b^(2))/(a^(2)-b^(2))(b)(a^(2)-b^(2))/(a^(2)+b^(2))(c)(a+b)/(a-b)(d)(a-b)/(a+b)

tan theta-cot theta=a and sin theta+cos theta=b(b^(2)-1)^(2)(a^(2)+4)

If tan theta=b, then cos2 theta+b sin2 theta=

If tan theta = a/b, then find sin 2 theta, cos 2 theta, "and" tan 2 theta.
