Homework Help: calculus

Posted by vector length on Tuesday, August 23, 2011 at 12:38pm.

Find a vector that has the same direction as the given vector but has length 6.
-2, -2, 4

I know how to find a unit vector of this, but to find a vector in the same direction but length >1 I'm not sure how to determine the scalar multiple that will be needed. I know it will be >1 because the length of the current vector is sqrt(24) and l=6 would be l=sqrt(36).

I tried using the multiple of sqrt(36/24) but it didn;t work.

Any help would be appreciated.'
