I did this: a b cos60/^2 and then multiplied the whole thing by 2 (because it is b) I wound up with an answer of 0.75. Is this correct?

**Derek**, Monday, June 30, 2008 at 9:15pmMy logic was this, as stated from a text book, which also showed your way: the projection of vector a onto b is found by (magnitude a)(magnitude b)(vector b) all over (magnitude b)2
