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:**

- 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.
- Substitute.
- Solve.
- Step 1: Choose which trig ratio to use.
- Step 2: Substitute.
- Step 3: Solve.
- Step 1: Choose the trig ratio to use.
- 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.
