Sketch the graph of function and show your solution
1. y= sin pi(x)/4
1st: Draw one period of a standard sine curve
2nd: Since the period is (2pi)/(pi/4) = 8, label the right end
of the sketch x = 8/2
3rd: Replicate that sketch to the right and to the left.

2. y= sin 4x
1st: Draw one period of a standard sine curve.
2nd: Since the period is (2pi)/4 = (1/2)pi, label the right end
of the sketch x = pi/2
3rd: Replicate that sketch to the right and to the left.
