Javascript Trigonometry

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
