Worthless
There is no way to input the vectors in the form of a formula. However, it does have a little "cheat sheet" that gives you various formulas, you just can't input your numbers in. Whats the point? The app just needs a lot more work to be user friendly.
Long awaiting app
I was waiting for some app like this to play with math
