1.	What is a well-conditioned system? How do you determine this mathematically? ANSWER Small perturbations in input don't result in large changes in output, so the solution is not sensitive to system parameters. 
cond(A) = ‖A‖‖A⁻¹‖ ≤ 1 
‖δx‖/‖x‖ ≤ cond(A) ‖δb‖/‖b‖ 
 
 
2.	What is the projection of vector y onto vector x? When is performing this useful? ANSWER proj_x(y)=(<x,y>/<x,x>)x
