Vector Helper is an app that can help you do various operations on two and three dimensional vectors.
-You can define the vectors by either their X and Y components or their Magnitude and Direction. Vector Helper will output both.
-You can Add, Subtract, and Dot Product 2 dimensional vectors and 3 dimensional vectors, and even cross product 3 dimensional ones!
Finally, Vector Helper will draw 2 dimensional vectors for you, helping you visualize sums and differences!
