What are the trigonometric identities?

In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.

Subsequently, one may also ask, how do you solve trigonometry?

There are three steps:
1. Choose which trig ratio to use. - Choose either sin, cos, or tan by determining which side you know and which side you are looking for.
2. Substitute.
3. Solve.
4. Step 1: Choose which trig ratio to use.
5. Step 2: Substitute.
6. Step 3: Solve.
7. Step 1: Choose the trig ratio to use.
8. Step 2: Substitute.

What are the formulas for sin cos and tan?

The functions of sin, cos and tan can be calculated as follows: Sine Function: sin(θ) = Opposite / Hypotenuse. Cosine Function: cos(θ) = Adjacent / Hypotenuse. Tangent Function: tan(θ) = Opposite / Adjacent.

What are the trig functions?

In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. The most familiar trigonometric functions are the sine, cosine, and tangent.
