Two waves are traveling in opposite directions on the same string. The displacements caused by the individiual waves are given by y1=(27.0 mm)sin(5.07πt - 1.72πx) and y2=(38.0 mm)sin(2.14πt + 0.229πx). Note that the phase angles (5.07πt - 1.72πx) and (2.14πt + 0.229πx) are in radians, t is in seconds, and x is in meters. At t = 5.90 s, what is the net displacement (in mm) of the string at (a) x = 2.30 m and (b) x = 2.99 m? Be sure to include the algebraic sign (+ or -) with your answers.
