Two waves are traveling in opposite directions on the same string. The displacements caused by the individual waves are given by y₁= (21.0 mm)sin(5.65mt-1.18mx) and y₂-(30.0 mm)sin(3.34mt+0.521mx). Note that the phase angles (5.65mt-1.18mx) and (3.34mt+ 0.521mx) are in radians, t is in seconds, and x is in meters. At t=2.20s, what is the net displacement (in mm) of the string at (a) x = 2.28 mand (b) x -2.92 m? Be sure to include the algebraic sign (+ or -) with your answers.
