I have a litte Vector Problem driving me nuts:
2 Vectors and the angle between them
(1)(2)
(2)(4)
(2)(4)
------ = 18/324 this with cos -1 and I have 0 degrees which is
3*6 what i expected they are collinear.
Now i normalize them and i have
angle = (v1) *(v2)
----------
1*1 <- omitted because 1*1 = 1
(1/3)(1/3)
(2/3)(2/3)= some crap unequal 0 degrees after cos -1
(2/3)(2/3)
could you tell me where my error is ?? is it logical or just typing ??? Thank you in advance
