### Description

The Trigonometric Function block performs numerous common trigonometric functions. You can select one of these functions from the Function list: sin, cos, tan, asin, acos, atan, atan2, sinh, cosh, and tanh. The block output is the result of the operation of the function on the input or inputs.

### Dialog box

- Function
  The trigonometric function.
