Distance Two insects are crawling along different lines in three-space. At time (in minutes), the first insect is at the point on the line Also, at time , the second insect is at the point on the line Assume that distances are given in inches.
(a) Find the distance between the two insects at time .
(b) Use a graphing utility to graph the distance between the insects from to .
(c) Using the graph from part (b), what can you conclude about the distance between the insects?
(d) How close to each other do the insects get?
