Click the green arrow to start! Click the blue button in the lower left to add a vector. Provide an amplitude (suggested to be 0-100) and a direction (suggested to be 0-360). The black line is the resultant. The colorful ones are the ones you've provided. Explanation: Vectors are a way of showing movement, using an amplitude and direction. For example, someone can drive 70 mph N (90 degrees), or push down (270 degrees) on something using 50 lbs of force. When two or more vectors exist, you can add the vectors to find a resultant. Think of it this way: If you are lightly tugging a rope towards you, and your friend is yanking the rope away from you, the rope is going to move towards your friend. Resultants can be found by making the vectors into right triangles, adding the x and y values from each vector, and then find the amplitude by using the pythagorean theorem and the direction by using arctan(y/x).
I used code from my previous project (Graphing Right Triangles) to make this one. Future updates: * Fixing the 180 and 360 errors * Drawing a triangle at the tip * Scaling the whole graph to accomodate large amplitudes * Units
