" 12.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) , find the value of (a sin theta-b cos theta)/(asin theta+b cos theta)

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), 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=(a)/(b) then b cos2 theta+a sin2 theta=

If theta be a positive acute angle and tan theta=(a)/(b) , then find the value of (a sin theta-b cos theta)/(a sin theta+b cos theta).
