All angles below are in radians. An angle r in radians has measure 180 * r / Math.PI in degrees.

#### Sine

``Math.sin(r);``

### Output

a value between -1 and 1.

``Math.asin(r);``

### Output

arcsine (the reverse of the sine) of r.

``Math.asinh(r)``

### Output

the hyperbolic arcsine of r.

### Cosine

``Math.cos(r)``

### Output

a value between -1 and 1

``Math.acos(r);``

### Output

arccosine (the reverse of the cosine) of r

``Math.acosh(r);``

### Output

The hyperbolic arccosine of r.

### Tangent

``Math.tan(r);``

### Output

tangent of r.

``Math.atan(r);``

### Output

arctangent (the reverse of the tangent) of r

``Math.atanh(r);``

### Output

The hyperbolic arctangent of r

``Math.atan2(x, y);``

### Output

the value of an angle from (0, 0) to (x, y) in radians
