About this app
This lab has a Cartesian plane available where the user can draw five vectors, use the head-tail graph method, and find the resulting sum. You can also draw a vector of equal magnitude, but in the opposite direction. The goal of the lab is to find the magnitude of the vectors, the angle, and the components in X and Y.
