## Problem Statement

Two waves on a string are given by the following functions: $$y_1(x,t) = 4 \cos{(20t - 30x)}$$ $$y_2(x,t) = -4 \cos{(20t + 30x)}$$ where $x$ is in centimeters. The waves are said to interfere constructively when thier superposition $\left| y_s \right| = \left| y_1 + y_2 \right|$ is a maximum, and they interfere destructive when $\left| y_s \right|$ is a minimum.
