How do you find two times when y=-2 in the second cycle of the graph y=3sin(t*360/8)
Here's a graph, in degrees.....https://www.desmos.com/calculator/0p5qfluvjt
Note that there are many instances where these graphs intersect......if, by "second cycle," you mean when t > 0, the times are t ≈ 12.92 and t ≈ 15.071
