# Cosine/ Cos() Calculator

This cosine wave calculator calculates the cosine of an angle.

To use this calculator, it's very basic. A user just enters the angle into the form field and then clicks the 'Calculate' button.

This calculator can calculate the angle either in degrees or radians. By
default, if the drop-down menu is unchanged, the cosine of the angle will be calculated in
degrees. However, this can be changed to radians, so that the value can be input and computed
from radian value.

**Example Calculations**

**In Degrees**

cos(0°)= 1

cos(60°)= 0.5

**In Radians**

cos(1)= 0.5403

cos(2)= -0.4161
