Math and Numerical Functions Trigonometric Functions

There are six Trigonometric functions: Sine, Cosine, Tangent, Inverse Sine, Inverse Cosine,
and Inverse Tangent.
Sine, Cosine, and Tangent
When a Sine, Cosine, or Tangent function receives power flow, it operates on IN, whose units
are radians, and stores the result in output Q. Both IN and Q are floating-point values.
Figure 131
The Sine, Cosine, and Tangent functions accept a broad range of input values, where
