Two sine waves are described by y 1 = A sin (t + kx) and y 2

Two sine waves are described by y₁ = A sin (ωt + kx) and y₂ = A sin (ωt + kx + π/3). Plot graphs of y₁ versus t and y₂ versus t on the same axes for the point x = 0. Plot y versus t for the superposition of the two waves at x = 0 and estimate its amplitude.
