Potentially an easy Calculus proble

  1. Feb 16, 2009 #1
    1.) A point (1,2,3) and the equation (x-2)^2+(y-5)^2+(z-5)^2=56, find the line (in parametric equations) from that point to the center of the sphere.

    2.) Here is everything I have done

    I first made a vector from 1,2,3 to 2,5,5.

    <1,3,2>

    and then a parametric equation

    r(t)=<1,2,3>+t<2,5,5>

    was this the right process

    In other words, you have t multiplying the wrong vector.

    Ah yes, sorry about not responding right away. I got what he meant.
