1. Consider the following two position vectors: u = (1, 2, 0), U = (4, 3, 1) (a) Calculate the projection of u onto v. We will call this vector Proj up . (3 pts.) (b) From part (a) we found the vector Proj up. Draw this vector on the sketch below. (4 pts.) u (c) Find the length lu - Proj uil. (3 pts.) (d) Extra Credit: What is the shortest distance between the point located by u and the axis defined by v ? Explain. (2 pts extra credit)
