## What is Cosine of an Angle?

Cosine of an angle is a trigonometric function that calculates the ratio of the adjacent side of a right triangle to its hypotenuse. It is abbreviated as cos and is used extensively in mathematics, physics, and engineering to solve problems involving angles.

## Cosine of Angle Formula

The formula for finding the cosine of an angle is:

cos( α ) = \dfrac{\text{adjacent side}}{\text{hypotenuse}}

Where α is the angle, adjacent side is the side adjacent to the angle, and hypotenuse is the longest side of the right triangle.

### Example 1:

Let's say you have a right triangle with an angle of 45 degrees. To find the cosine of the angle, you can use our cosine of angle calculator. Simply enter 45 as the angle value choose degrees from the select box, and the calculator will tell you that the cosine of the angle is 0.7.

### Example 2:

Suppose you have a right triangle with an angle of 54 degrees. Using our cosine of angle calculator, you can find the cosine of the angle by entering 54 as the angle. The calculator will tell you that the cosine of the angle is 0.58.
