You should have gotten the following plot:

rab1plot=Plot[rab1,{t,0,10}, PlotStyle->Red]

Rabbit Plot

Observe the pattern in the graph! It looks like we're dealing with a periodic function here. (We only have two wavelengths of it, I know, but trust me, it keeps repeating!)

Now it's your turn. Make a similar plot of fox1, but make this one green. Assign it the name fox1plot. No, I'm not going to type the command for you! Simply change rab to fox in both places it occurs in the command we just completed.

Now let's go see what you should have gotten...
