## cos0

### 1

The value of cos(0) is 1.

In trigonometry, cos(x) represents the value of the cosine function for an angle x expressed in radians. The cosine function represents the ratio of the adjacent side of a right triangle to the hypotenuse.

When the angle is 0 degrees or 0 radians, the adjacent and the hypotenuse sides of the right triangle coincide. This means that their ratio is equal to 1, resulting in cos(0)=1.

Therefore, cos(0) is equal to 1.
