" If "tan theta=(a)/(b)," then "b cos2 theta+a sin2 theta" is equal to "

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

if tan theta=(a)/(b), then cos2 theta+a sin2 theta equal to

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

If a tan theta = b, then a cos 2 theta+ b sin 2 theta =

If tan theta=a/b then b cos 2theta+asin 2theta=

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

if tan theta=(x)/(y) then sin2 theta+cos2 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)
