This operator performs a variety of trigonometric functions. The argument must be expressed in radians.
The frequency/offset make most sense for the sin(), cos(), and tan() trigonometric functions. The frequency multiplies the input radians while the offset is added to the result of the frequency scale.
For anti-aliased sine and cosine waves, see the Oscillations operator, which is available in all shading contexts.
acos computes the arc-cosine of the argument. The return value is in the range 0 to PI.
asin computes the arc-sine of the argument. The return value is in the range -PI/2 to PI/2.
atan computes the arc-tangent of the argument. The return value is in the range -PI/2 to PI/2.
cos computes the cosine of the argument.
cosh computes the hyperbolic cosine of the argument.
sin computes the sine of the argument.
sinh computes the hyperbolic sine of the argument.
tan computes the trigonometric tangent of the argument.
tanh computes the hyperbolic tangent of the argument.
