**Reiny**, Monday, May 27, 2013 at 9:32ampick any value of s and t you feel like, I will do one

let s = 2, t = 1

(x,y,z) = (3,4,-1) + (2,2,-8) + (2,-5,3) = (7, 1, -6) - vectors -

**Reiny**, Monday, May 27, 2013 at 1:22pmIt said, find three points, that is

any three point from the infinite number of points that would be possible

to get my point, as I said, I let s=2 and t=1

to get their point of (3,4,-1), they used s=0 and t=0

to get their point of (4,5,-5) they used s=1 and t=0

You can use any value of s and t that you want, it was rather silly to even give any answer at all in the back of the book.

It only confuses the student if he/she does not get that particular answer.
