The nodes in this section are all concerned with angular values.

ArcCos

The ArcCos node takes the inverse cosine of the input scalar. The input can be in the range -1.0 to 1.0 for a real result. The result will be in the range PI to 0. If the input is not in range, the result will be an invalid floating point value.

Example: cos(x) = y implies arccos(y) = x

ArcSin

The ArcSin node takes the inverse sine of the input scalar. The input can be in the range -1.0 to 1.0 for a real result. The result will be in the range -PI/2 to PI/2. If the input is not in range, the result will be an invalid floating point value.

Example: sin(x) = y implies arcsin(y) = x

ArcTan

The ArcTan node takes the inverse tangent of the input scalar. The input can be any scalar value. The result will be in the range -PI/2 to PI/2.

Example: tan(x) = y implies arctan(y) = x

Cos

The Cos node takes the cosine of the input scalar.

Sin

The Cos node takes the sine of the input scalar.

Tan

The Cos node takes the tangent of the input scalar.
