Document Summary

Here is what you are expected to know for the nal. You will be asked to do problems such as: Find the line of intersection of two given planes. Find the distance from a given point to a given line in space. I strongly prefer using cross product (see my solution to the rst midterm), but there are other (mostly long and confusing) methods too. Find the line going through a given point and parallel to a given line. Find the equation of a plane going through three given points in space. Find the heights of a given triangle in space. For this you just need to know how to nd the distance from a point to a line. For this you need to use the dot product. For this you need to nd the angle between the normal vectors (using dot product): polar coordinates. Write a point given in cartesian coordinates in terms of polar coordi-
