Cot 2+tan 2 1
WebTrigonometric Identities. Trigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved. Some of the most commonly used trigonometric identities are derived from the Pythagorean Theorem , like the following: sin2(x) + cos2(x) = 1. 1 + tan2(x) = sec2(x) Web79k 8 75 154. Add a comment. 1. You would solve it with the identity cot 2 x + 1 = csc 2 x, you substitute that, and then simplify the fraction. cot 2 x + 1 cot 2 x. = csc 2 x cot 2 x. = 1 sin 2 x cos 2 x sin 2 x. = sin 2 x cos 2 x ∗ sin 2 x. = 1 cos 2 x = sec 2 x.

WebIf \( \tan ^{-1}\left(\sin ^{2} \theta-2 \sin \theta+3\right)+\cot ^{-1}\left(5^{\sec ^{2} y}+1\right)=\frac{\pi}{2} \), then the value of \( \cos ^{2} \thet... Web4 Answers. cot 2 x + sec 2 x = cos 2 x sin 2 x + 1 cos 2 x = cos 4 x + sin 2 x cos 2 x sin 2 x. tan 2 x + csc 2 x = sin 2 x cos 2 x + 1 sin 2 x = sin 4 x + cos 2 x cos 2 x sin 2 x. Now there are various ways to see it. Of course it is easier knowing the standard identities and using them, but they all pretty much boil down to sin 2 x + cos 2 x ...
Websin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. …
