Best Answer

The trigonometric functions: sine, cosine, tan as well as their reciprocals are periodic so that their value repeats every 2Ï€ radians. As a result, the inverse operations are functions only over restricted domains, as follows.

Sine : âˆ’Ï€/2 â‰¤ y â‰¤ Ï€/2

Cosine: 0 â‰¤ y â‰¤ Ï€

Tangent: âˆ’Ï€/2 < y < Ï€/2

The principal value is the angle that lies within the relevant range. All other solutions are non-principal.

Similarly, the principal square root of a positive real number is the positive square root. The negative root is not the principal root.

The basic principle of trigonometry is that there are mathematical relationships between the sides and angles of a triangle.

plane trigonometry spherical trigonometry

It is ln[1+sqrt(2)] = 0.8814, approx.

The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.

The answer depends on what x is meant to represent. Without that information, the question is a waste of time.
