Theory
A graph of periodic function f(x) that has period L exhibits the
same pattern every L units along the x-axis, so that f(x+L) = f(x)
for every value of x. If we know what the function looks like over one
complete period, we can thus sketch a graph of the function over a
wider interval of x (that may contain many periods)
Tips on using solutions
When looking at the THEORY, ANSWERS, INTEGRALS, TRIG
or NOTATION pages, use the Back button (at the bottom of the
page) to return to the exercises
Use the solutions intelligently. For example, they can help you get
started on an exercise, or they can allow you to check whether your
intermediate results are correct
Try to make less use of the full solutions as you work your way
through the Tutorial
