Homework Statement
The position of a spaceship is:
[tex] r(t)=(3+t)i +(2+ln(t))j+(7-\frac{4}{t^2+1})k[/tex]
and the coordinated of the space station are (6,4,9). The captian wants the spaceship to coast into the the space station. When should the engines be turned off?
Homework Equations
[tex] r(t)=(3+t)i +(2+ln(t))j+(7-\frac{4}{t^2+1})k[/tex]
The Attempt at a Solution
Ok the ship coasts(uniform velocity) into the space ship.
So max/min problem right? Find [tex] \frac{d^2r}{dx^2}[/tex] set equall to zero and solve for t right?
