Evaluate for `theta`
`( Sin(theta ) + Cos(theta ) )/ ( Sin(theta ) - Cos(theta ) )` = `5/4`

4 sin theta * cos^(3) theta-4 cos theta * sin ^(3)theta= A) 4 cos theta B) cos 4 theta C) 4 sin theta D) sin 4 theta

Evaluate: int cos2 theta ln((cos theta+sin theta)/(cos theta-sin theta))d theta

(1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)

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

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

If 3 cot theta = 4 , find the value of (5 sin theta - 3 cos theta)/(5 sin theta + 3 cos theta) .

If 5 cot theta = 3 ," find the value of "((5sin theta - 3 cos theta )/(4 sin theta + 3 cos theta)).

If sin theta+cos theta=a, then sin^(4)theta+cos^(4)theta=
