Question

If A is invertible, i.e., for any given r.h.s. vector b, the system Ax = b has a solution. How can you compute the 3rd column of A^−1(what r.h.s. b would youchoose)?

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
