Vector Problem

  1. May 29, 2007 #1
    1. The problem statement, all variables and given/known data
    The equation X(t)=A+tL is the parametric equation of a line through the point P:(2,-3,1). The parameter t represents distance from point P, directed so that the I component of L is positive. We know that the line is orthogonal to the plane with the equation 4x-6y+5z=6. Then solve for A and L in vector component form.


    2. Relevant equations

    Standard Vector Calculus equations.

    3. The attempt at a solution

    My problem here is simply understanding what the problem is saying. The t term is throwing me off. Hopefully some of you could shed some light on this.

    t is a number - like x in the 2d straight line equation y=m*x+b. L is analogous to the slope m. So as t runs from -infinity to infinity X(t) runs through a curve of points. That curve is a straight line.
