1. The problem statement, all variables and given/known data We are doing vectored valued functions currently in calculus. The Problem is: The position function of a spaceship is R(T)=<3+T, 2+ln(T), 7-(4/(T2+1)) and the coordinates of a space station are (6, 4, 9). The captain wants to coast into the space ship. When should the engines be turned off? 2. Relevant equations The position function of the spaceship is R(T) = <3+T, 2+ln(T), 7-(4/(T2 +1)> 3. The attempt at a solution I think I need to take the derivative to get the velocity function. The only problem is it is hard to find the correct location in which the velocity vector would be parallel, and on point to the space station.
