The FORCOS function evaluates a Fourier Cosine series at a user-specified value x. The x0, a0, a1,...,a30 are parameters used to define the constants for the Fourier Cosine series.

A real variable that specifies the independent variable. For example, if the independent variable in the function is time, x is the system variable TIME. A real variable that specifies the fundamental frequency of the series. Adams/Solver (C++) assumes w is in radians per unit of the independent variable unless you use a D after the value. MOTION/1, JOINT=21, TRANSLATION,

, FUNCTION=FORCOS(TIME, 0, 360D, 1, 2, 3, 4)This MOTION statement defines a harmonic motion as a function of time. The motion has no shift, has a fundamental frequency of 1 cycle (360D) per time unit, has a constant value of 1.0. The function defined is:
