Math.Tests.Cosh ​

Computes the hyperbolic cosine of constant and time-varying inputs.

Connects a constant source with value 0 to a Cosh block and verifies that cosh(0) = 1. A second Cosh block is driven by a sine wave (amplitude 3) that sweeps negative and positive values.

Usage ​

BlockComponents.Math.Tests.Cosh()
