Cosine of a Cubic Polynomial
Plot of . In general, the larger the argument of a trigonometric function, the faster the function will oscillate. Near zeros of the derivative of the argument, the argument does not change much and the trigonometric function will have smaller variations.



, , — coefficients of the linear, quadratic, and cubic terms
