## Unit Vector

vector = [1 2 3;4 5 6; 7 9 0] vector = 1 2 3 4 5 6 7 9 0 I want to take this and create a unit vector. We can get the magnitude by doing: mag = sqrt(sum(vector'.^2))' mag = 3.7417

## Our people say

All in all, it's amazing and I would definitely recommend this to anyone. Although some problems i had to rewrite them for the app to solve them, and obviously it couldn't do word problems. AmazingĀ©, best math app very helpful but it not free. Great job, highly recommend this app.

## Finding the Unit Vector of a Vector

Well, the unit vector i goes in the exact same direction. But the x component of this vector is just a lot longer. It's 10 cosine 30 degrees long. And that's equal to-- cosine of 30 degrees is square root of 3/2 --so
