Hi kathrynag!

My problem is that I don't even understand what a locus is..

You get plagues of locuses … they're the curves described by the Israelites when they left Egypt.

At t = 0, Moses was at position z1, and at t = 1 he was at position z2 …

so where was he at a general time t, between 0 and 1? ​
