how to plot sine graph
When you do your sine graphs, don't try to plot loads of points. Instead, note the important points. The sine wave is at zero (that is, on the x-axis) at x = 0, Ï, and 2Ï; it is at 1 when x = Ï/2; it is at â1 when x = 3Ï/2. Plot these five points, and then fill in the curve.
