We can think of the lines that make up our c and e variables as nothing more

6-4
).
Think of these two lines as parts of a triangle that give us two nice and
simple equations for determining the value of our c and e variables. Because
two of the sides of our right triangle are equal to our value for x and y,
finding the value of c is really easy. Finding the value of e is also pretty
straightforward—the height of the second right triangle is the same, so we
keep the y value. The length of the base of the second right triangle is equal
to the length ...
