Consider g(x)=3sin2x a) period of g b) sketch the curve of g, for 0≤x≤2π -without using a graphing calculator

The sure thing about the graph is that the amplitude is at 3 and -3. Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
