Document Summary

When you add 2 or more vectors they must be of the same. A vector from one point to another can be found by the difference of the points. 2 x n y n t x t x x. R-space ( )9 ordered 1-tuple, a single point. )5, 2 ordered 2-tuple, 5 is the first position, 2 is the second. 1, 2, 3 ordered 3-tuple n ordered n-tuple. +, - symbols represent direction (in general left and down is - . From the origin, go x1 units, from x1 go x2 units, from x2 go x3 units, then from xn-1 go xn units. )n y you can find the distance dist(p,q) = x. Are parallel if one of the following applies: there is a number t with y tx= , there is a number s with x ty= . 4 , , 0, 3 t t t. No number t can make the left side equal to the right side.
