The teachers   In a right triangle, the following trigonometric ratios can be defined:

### Sine

The sine of the angle B is the ratio between the length of the opposite side and the hypotenuse of the triangle.

It is denoted by sin B. ### Cosine

The cosine of the angle B is the ratio between the length of the adjacent side and the hypotenuse of the triangle.

It is denoted by cos B. ### Tangent

The tangent of the angle B is the ratio between the length of the opposite side and the adjacent side of the triangle.

It is denoted by tan B. ### Cosecant
