Description
The Trigonometric Function block performs numerous common trigonometric functions. You can select a function among those quoted in this table :
| Function | Definition | Output |
| sin | Sine of the input (radians) | y = sin(u) |
| cos | Cosine of the input (radians) | y = cos(u) |
| tan | Tangent of the input (radians) | y = tan(u) |
| asin | Inverse sine (radians) of the input | y = asin(u) |
| acos | Inverse cosine (radians) of the input | y = acos(u) |
| atan | 2-quadrant and 4-quadrant inverse tangent (radians) of the input | y = atan(u) |
| sinh | Hyperbolic sine of the input | y = sinh(u) |
| cosh | Hyperbolic cosine of the input | y = cosh(u) |
| tanh | Hyperbolic tangent of the input | y = tanh(u) |
The block output is the result of the applied function on the scalar input or on the vector's elements of input.
