# What are the quotient identities for a trigonometric functions?

As below

Quotient Identities. There are two quotient identities that can be used in right triangle trigonometry.

A quotient identity defines the relations for tangent and cotangent in terms of sine and cosine. ...

.

Remember that the difference between an equation and an identity is that an identity will be true for ALL values.

The quotient identities for trigonometric functions are:

- (\tan(x) = \frac{\sin(x)}{\cos(x)})
- (\cot(x) = \frac{\cos(x)}{\sin(x)})
- (\sec(x) = \frac{1}{\cos(x)})
- (\csc(x) = \frac{1}{\sin(x)})

These identities are fundamental in trigonometry and are used to express one trigonometric function in terms of others.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
