Prove that, the function `(sin theta+2 cos theta)/(3 sin theta+4 cos theta)` decreases for all real values of `theta`.

If sin theta = cos theta then 2 theta =

(1+sin2theta+cos2theta)/(1+sin2theta-cos2theta)=?

If A=sin^2theta+cos^4theta then for all real values of theta

Prove that, (1 + sin 2 theta - cos 2 theta)/(sin theta + cos theta)= 2 sin theta

If sin2 theta = cos 3 theta then theta =

Prove that : (1+ sin theta - cos theta) / (1+ sin theta + cos theta ) = tan (theta/2)

If sin theta = cos theta , what is sin theta - cos theta = ?

Show that, for all real values of theta the function (2 sin theta+ cos theta)/(3 sin theta+ 4 cos theta) is increasing.

If (sin theta+cos theta)/(sin theta- cos theta) = 3/2 then cos theta =

Prove that, (sin 3 theta)/(sin theta)-(cos 3 theta)/(cos theta)=2
