Math.Tests.Cos

Computes the cosine of constant and time-varying inputs.

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

Usage

BlockComponents.Math.Tests.Cos()
