Trigonometry is one of the most important fields of the mathematics which mainly deals with the degrees and it's related mathematical components.

In the trigonometry,

The ratio of the base and hypotenuse of a right angle is known as the cosine or cos.

Now, the value of cosine or cos is dependent on the angle related with it.

For example,

cos0° = 1

cos30° = ✓3/2

cos45° = 1/√2

cos60° = 1/2

cos90° = 0
