Question 455832: Describe the graph of the function y+=+3+sec+%28expr%281%2F4%29x%29

You can put this solution on YOUR website!
y+=+3sec%28expr%281%2F4%29x%29
We find the length of a period by dividing
2pi by 1%2F4
2pi%2F%281%2F4%29=2pi%2Aexpr%284%2F1%29=8pi
So we want to draw the graph from 0 to 8pi
Divide 8pi by 4 to get 2pi so we mark
the graph off in units of 2pi
