    The amplitude is half the difference between the max value and min value. The max value here is 3 and the min value is -3. So A=(3--3)/2=3. The period is the time it takes for the graph to complete one cycle. Here, it completes one cycle between negative pi and pi, so the period is 2pi.

    not sure if they count shift in up and down as phase shift too.. but theres no phase shift in your problem anyway, as it hasnt moved up or down or left or right
