This is a calculus 3 problem and I need to find a vector in the third dimension but I need to do this without using the dot or cross product. So I am asked to find:
A unit vector u parallel to the vector with initial point (6,6,7) and terminal point (-3,3,10)
So to do this I think I need to combine the initial point and terminal point:
So that means v=<-3-6,3-6,10-7) which means that v=<-9,-3,3>
But after that, I do not know how to find this answer. I think I need to find the magnitude which I get to equal
√(99). But this is the last thing I have any clue how to do.
Thanks you for the help
