WebNow, that we have derived cos2x = cos 2 x - sin 2 x, we will derive cos2x in terms of tan x. We will use a few trigonometric identities and trigonometric formulas such as cos2x = cos 2 x - sin 2 x, cos 2 x + sin 2 x = 1, and tan x = sin x/ cos x. We have, cos2x = cos 2 x - sin 2 x = (cos 2 x - sin 2 x)/1 = (cos 2 x - sin 2 x)/( cos 2 x + sin 2 x) [Because cos 2 x + sin 2 x = 1]. … WebThe reciprocal trigonometric ratios Sine & cosine of complementary angles Google Classroom Learn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°.
