If A, B and C are interior angles of a triangle ABC
Express the trigonometric ratios sin A, tan A and sec A in terms of cot A
1 + tan cube theta / 1 tan theta + tan theta - sec square theta = 0
Prove the trigonometric identity
Express each of the following in terms of trignometric ratio of angles
tan theta - cot theta = 2 sin square theta - 1/sin theta cos theta
2 (sin (power 6) theta + cos (power 6) theta) - 3 (sin (power 4) theta + cos (power 4) theta) + 1 = 0
(cosec theta - sin theta) (sec theta - cos theta) = sin theta . cos theta
