what is cos 90 x Why does cos 90 x sin x and sin 90 x cos x Solution Trigonometric identities are equations that relate to different trigonometric functions and are true for all the
The cosine function of an angle is equal to the length of the adjacent side divided by the hypotenuse side and the value of cos 90 degrees is So sin x 90 cos x You could also flip sin x around the y axis that is replace x with x then shift right by 90 A right shift by 90 changes x to x 90
