Also the notation for squaring trigonometric function 2018-07-11 First, multiply the left hand side by (sinx + cosx) / (sinx + cosx) leaving the numerator factored, but multiplying out the denominator. Next, use the identity sin 2 (x) + cos 2 (x) = 1 to simplify the denominator. Hope this helps, Stephen La Rocque If units of degrees are intended, the degree sign must be explicitly shown (e.g., sin x°, cos x°, etc.). Using this standard notation, the argument x for the trigonometric functions satisfies the relationship x = (180x/π)°, so that, for example, sin π = sin 180° when we take x = π. 2019-12-20 2007-12-07 2 sinx siny= 2sin x y 2 cos x+y 2 cosx+ cosy= 2cos x+y 2 cos x y 2 cosx cosy= 2sin x+y 2 sin x y 2 The Law of Sines sinA a = sinB b = sinC c Suppose you are given two sides, a;band the angle Aopposite the side A. The height of the triangle is h= bsinA.

You can combine the first and last terms using a trigonometric identity-- sin^2 x + cos^2 x = 1. 1 + 2 sin x cos x. Another identity is that 2 sin x cos x = sin 2x, so you end up with. 1 + sin 2x Cos^2 + Sin^2 = 1^2 = 1 StupidLemonEater commented July 25, 2020 Here’s another proof: if you have a right triangle with side lengths a, b, and c (where c is the hypotenuse) then the sine of the angle opposite side a (let’s call it x) is equal to a/c.
