lf Sin`theta` = `3/5` then Cos`theta` =

If sin theta=3/5 then cos theta will be

(sin5 theta-2sin3 theta + sin theta) / (cos5 theta-cos theta) = tan theta

If 3 sin theta + 4 cos theta = 5 , then 3 cos theta - 4 sin theta is equal to?

Prove that (sin theta + sin 3theta+ sin 5 theta + sin 7theta)/(cos theta + cos 3theta + cos 5 theta + cos 7theta) = (tan 3theta + tan theta)/(1 - tan 3theta tan theta) .

If 5 tan theta =4 , then frac(5sin theta - 3cos theta )(5 sin theta + 2cos theta ) is equal to

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:

If 3 sin theta + 4 cos theta =5 , then value of sin theta is
