Homework Statement
I can find the graphs amp and period. The only problem is finding the sub points or sub intervals. Say...
Y = 3 sin (4x)
Amp = 3
Period = 2pi/4 = pi/2
But.. don't know how to get the key points of the sub interval. The textbook says I have to divide interval [0, pi/2] into four sub intervals Each of length pi/2 divided by 4. Then they got (0,0), (pi/8, 3), (pi/4, 0), (3pi/8, -3), (pi/2, 0) I don't understand how they got these. Thanks
