Question

Let L be the line passing through the point P=P(−1, −5, −5) with direction vector →d=[−2, −3, 3]T. Find the shortest distance d from the point P0=P0(−3, −2, 2) to L, and the point Q on L that is closest to P0.

Answer 1

What math is this, calc 3 ?

Answer 2

linear algerbra!

Answer 3

I was thinkig we can find Q by Q= P-P0 and find Q. then we project it with Q= proj Q onto D
