##### The six identities used in trigonometry

As was said above, there are six important identities in trigonometry. We’ve looked at the values of these identities from different points of view up until now. In this section, we’ll find out more about who these people are.

**Sine Function**

- The sine function is the first. The sine function of an angle is the ratio between the length of the side opposite the angle and the length of the hypotenuse. Sine’s value can also be written as:
- Sin a = opposite / hypotenuse = CB / CA

**Cos Function**

- The cos function of an angle is the ratio of the length of the side next to the angle to the length of the hypotenuse. This means that you can write the cos function as:
- Cos a = Adjacent / hypotenuse = AB / CA

**Tan Function**

- The tan function, also called the tangent function, is the ratio of the length of the opposite side to the length of the side next to it. Students should remember that tan can also be shown in the form of a ratio using the values of sine and cos. From this information, we can say that the value of a tan function can be:
- Tan a = opposite / adjacent = CB / BA
- Or Tan = sin a + cos a

There are three main functions: sine, cos, and tan. Aside from these main functions, the other trigonometric functions are secant, cosecant, and cotangent. You can also think of these extra functions as the opposite of the sine, cos, and tan functions. The reciprocal of the sine function is the cosecant, and the reciprocal of the cos function is the secant. The reciprocal of the cot function is the cotangent.

Here are the formulas for all of these other functions:

- Sec a = 1 / cos a = hypotenuse / adjacent = CA / AB.
- Cosec a = 1 / sin a = hypotenuse / opposite = CA / CB.
- Cot a = 1 / tan a = Adjacent / opposite = BA / CB.

## FAQ ( Frequently Asked Questions )

**1. What are the Trigonometry Ratios Formulas?**

Ans – Here are the formulas for the three most important trigonometric ratios.

- Sin a = perpendicular / hypotenuse.
- Cos a = base / hypotenuse.
- Tan a = perpendicular / base.

**2. Name the three most important function of trigonometry.**

Ans – Trigonometry has three main functions: sin, cos, and tan.
