Add and subtract vectors

What you'll learn

1. Add two vectors graphically using the head-to-tail (end-to-end) method.
2. Add two vectors graphically using the parallelogram rule.
3. Add vectors component-wise and verify the result agrees with graphical methods.
4. Explain why the magnitude of a sum of two vectors is typically not the sum of the magnitudes.
5. Given two vectors in magnitude-and-direction form, find the magnitude and direction of their sum.
6. Define vector subtraction as adding the additive inverse; represent subtraction graphically and component-wise.
