... same ω and A.) Two phases that differ by 2π are effectively the same phase. Be careful with the sign of the phase. Fig. 4 shows plots of A cos(ωt + φ), for φ = 0, ±π/2, and π. Note that the plot for φ = +π/2 is shifted to the left of the plot for φ = 0, whereas the plot for φ = −π/2 is shifted to th ...
