# CURVE:QUARTIC

Quartic (fourth order polynomial) curve with one independent variable. Input for a Quartic curve consists of the curve name, the five coefficients, and the maximum and minimum valid independent variable values. Optional inputs for curve minimum and maximum may be used to limit the output of the performance curve. curve = C1 + C2*x + C3*x**2 + C4*x**3 + C5*x**4
