Any help would be appreciated.
Consider a line L which goes by a point Q and is parallel to a vector v. Let P be any point and let R be its mirror image across the line L.
(a) Find a formula for R starting from P, Q and vector v. Sketch your construction.
(b) Assume that P(1, 6, 2), Q(-4, 1, 2) and vector v = <-2,-1,5>. Find R. Tue, 29 Jan 2013 23:36:18 +0100https://ask.sagemath.org/question/9752/linear-algebra-point-and-line/Comment by ppurka for <p>I have been having difficulty with this problem. Any help would be appreciated.
