In this lecture you will learn how to use the Midpoint and Distance Formulas. Professor Fraser will walk you through how to use both the Midpoint Formula and Distance Formula with several examples and ending the lecture with four full worked out video examples.
Make sure that you
know and understand how to use both of these formulas. They will be
used in a lot of later work.
Remember that the
order of the x coordinates in the distance formula does not matter.
So take whichever difference is easier to compute. The same comment
applies to the y coordinates.
After squaring the
differences in the distance formula, be sure to take the positive
square root of their sum.
