Ex: Forgetting to normalize the unit vector. - 3 Wrong equation Ex: Forgetting to square the magnitude components under the root sign. - 5 Returning a vector answer for a dot product calculation. For incomplete work give the points commensurate with the percentage of the overall work done. Example: If a 35 point problem has 7 steps and they complete 2 of the steps, give them 10 points. Don't take off more than what the problem is worth! Make sure they end up with at least 5 points for trying on an exam and 2 points for trying on a homework problem. (If they did try . . .)
