How to calculate this point?

  1. Apr 17, 2008 #1
    Hi all:

    Given a line L:v= v0+t*n; and two points A, B in 2D plane; A and B are on the two sides of the line L. I want to calculate the point C which makes AC is perpendicular to BC

    I know it's simply that substitude v to C and <AC, BC>=0. But I don't know how to simplify the equation.

    Could anyone help me please?

    should this |v0- t*n|2- <v0+ t*n,A+B>+ <A,B>

    be <v0+t*n, v0+t*n> - <v0+t*n, A+B> + <A, B> ???
