What are the trigonometric identities?
They are sine, cosine, tangent, cosecant, secant, and cotangent. All these trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. All the fundamental trigonometric identities are derived from the six trigonometric ratios.
What is cos 2x?
Cos2x is one of the double angle trigonometric identities as the angle in consideration is a multiple of 2, that is, the double of x. Let us write the cos2x identity in different forms: cos2x = cos2x – sin2x. cos2x = 2cos2x – 1.

What is the inverse of cos?
Since arccos is the inverse of the cosine function, and many angles share the same cosine value, arccos is a periodic function. Each arccos value can result in multiple angle values. The primary result for arccos is known as the principal value and is the angle in the range of 0° to 180°.
