I don't have any of my math books here, but I am reading in a game programming book about vectors, but I can't get the same result as the authour. I am getting something else all the time.

I'll give a rep to the first guy that gets the same result as me or the authour for these vectors:

v1 = [1.5, 3.0, 4.0]
v2 = [4.0, 1.0, 2.0]


PS: Please give the angle in both Rad and Deg.

Thanks
