In this lesson we’ll look at points that are plotted three-dimensionally and how to find the distance between them. We’ll use the distance formula in three dimensions, plug in the two points, and then simplify the square root in order to calculate the distance.
Read MoreBefore you can use the distance, rate, and time formula, D=RT, you need to make sure that your units for the distance and time are the same units as your rate. If they aren’t, you’ll need to change them so you’re working with the same units.
Read MoreAny point in the coordinate plane can be expressed in both rectangular coordinates and polar coordinates. Instead of moving out from the origin using horizontal and vertical lines, like we would with rectangular coordinates, in polar coordinates we instead pick the angle, which is the direction, and then move out from the origin a certain distance.
