### Dr. Sarah's Comments and Peer Review for Keith and Sarah's Number 2

### Dr. Sarah's Comments

Good, but should reconcile the 2 plots (one looks like a
set of increasing straight lines, while the other looks like a
plot where some of the solutions decrease and then increase.
Notice that these plots do not contradict each other - the
first is a zoomed in version of the second.
### Peer Review

Good, but which graph is right?

Thought it was good to try by hand, but Anthony's and John T's way of
manipulation for calculations was a bit better

Impressed that they checked by hand-good job,
but confused on the last graph

They did a good job, but their answers are different than Jon T and
Anthony.

Good job, well organized presentation and worksheet

Looks good, but I don't really know what is going on.

Different solution for part c? What's this plot? Now I'm really confused

Good job with the math! The trouble manipulating Maple is understandable!

Good presentation

Good idea to also try to solve by hand. Final graph looks better than
other groups apart from who is correct.

Good by hand work. Good job on the maple that they did right.

Why did it differ from John and Anthony?

Liked the fact they started by hand, speak up, it's hard to go over
something right after someone else goes over it.

Very good maple presentation. I thought the presentation was easier to un
derstand then the other problem #2. I still don't understand the
evaluation of different x values and the graph.

Kind of foggy as to if you were clear on how to do this. o.k.

They also did good, although much of their
calculations seemed to be erroneous.

They also did well on #2, but their maple work was a little different.

Good worksheet, nice touch working by hand

Too quiet to hear. All presentations went too fast

Good comments on Maple

You might want to check spelling. You might want to put into
text that you solved by first order linear.

Still looks complicated, but it was good.
