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

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

If a cos theta-b sin theta=c, then find the value of a sin theta+b cos theta

If a cos theta-b sin theta=c, then find the value of a sin theta+b cos theta

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

If 5 tan theta =4 then find the value of (5 sin theta - cos theta)/(sin theta + 3 cos theta)

If tan theta=a/b , then the value of b cos 2theta+asin 2 theta is

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

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

If sin theta =(3)/(5) and theta is acute, then find the value of (tan theta - 2 cos theta )/(3sin theta+sec theta ) .
