" 1.(a) If tan "theta=(a)/(b)" ,then find the value of "b cos2 theta+" a sin "2 theta" ."

If tan theta=(b)/(a), then find the value of a cos2 theta+b sin2 theta

If tan theta=(b)/(a), find the value of a cos2 theta+b sin2 theta

If tan theta = b/a, then find the value of a cos 2theta + b sin 2theta .

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

If tan theta=(a)/(b), where 0 a>0, find the value of sin2 theta,cos2 theta and tan2 theta

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

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 find sin 2 theta, cos 2 theta, "and" tan 2 theta.

If sin theta = cos theta , then find the value of 2 tan theta + cos^(2) theta .
