1. A long straight copper wire extends through the points (0,0,0)? and (1,2,3)7 in R3. (The wire is much longer than the distance between these two points.) The wire is maintained with a positive electrical charge. A cosmic ray ionizes a nearby argon atom located at = (x\, x2, x3)7, which produces a free electron. The electron, being negatively charged, flies straight toward the positively charged wire. It crashes into the copper wire at the point Pt. What is the matrix P? Hint: Use the formula for orthogonal projection from least squares solutions: P A(A*A)A
