# Cosine Ratio Identity Calculator

The cosine divide formula is defined from the ratio identity of tangent. Tangent function is the ratio of sine function to cosine function, which is known as ratio identities. In this calculator, the sine divided by the tangent function is used as the formula to calculate the cosine function.

#### Cosine Equals Sine Divide Tangent

### Cosine Ratio Identity Formula :

cos (α)

= sin (α) / tan (α)

Use this cosine equal sine divide tangent product calculator to find cosine function value by just entering the α value which also helps to calculate the sine and tangent function value.
