1/22/2021 Slide 1 Combined sine, adjust phase and frequency Make a plot_ly plot, combining two sine waves with nearby frequencies through multiplcation. Give controls over the phase of the second sine wave. See what it does to the result. Trig identity: cos(α + β) = cos(α) cos(β) – sin(α) sin(β) Rearranged: sin(α) sin(β) = cos(α) cos(...
