Trigonometry math nodes

Acos

Outputs the arc cosine of the given input.

The arc cosine is the angle whose cosine is the given input.

The output will be in the range 0 to PI.

Asin

Outputs the arc sine of the given input.

The arc sine function is the inverse of the sine function.

The output is in the range -PI/2 to PI/2.

Atan

Outputs the arc tangent of the given input.

The arc tangent is the angle whose tangent is the given input.

The output is in radians and is in the range -PI/2 to PI/2.

Use the atan2 node to get the angle in the range -PI to PI.

Atan2

Outputs the arc tangent of the given input.

The arc tangent is the angle whose tangent is the given input. It computes the unambiguous value for the angle a in converting from

Cartesian coordinates (x, y) to polar coordinates (r, a) where x = r * cos(a), y = r * sin(a) and r^2 = x^2 + y^2

The output is in radians and is in the range -PI to PI.

Cos

Outputs the cosine of the given angle in radians.

The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Pi

Outputs the number PI constant as an angle (180 degrees).

Sin

Outputs the sine of the given angle in radians.

The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

Tan

Outputs the tangent of the given angle in radians.

The tangent of an angle is the ratio of the length of the opposite side to the length of the hypotenuse to its adjacent side.
