How the Grinch Stole Calculus!

Ashley Tucker and Emily Pottkotter

• He adds and divides, he subtracts and timeses,

But his numbers are forced like very bad rhymses

4+4=6,9-3=8,

Think that’s bad?

It gets worse!

You just wait

To see these numbers’ horrible fate.

3 times 3 is a hundred and thirty thirteen!

No sir, his math, it isn’t quite clean,

It’s gone through some kind of distorting machine

Making thin numbers fat and fat numbers lean.

His name is the Grinch and he is so, so mean!!

Here’s the Problem. Solve ‘em!

• The Grinch lives high on Mt. Crumpit overlooking Whoville. Little Cindy Lou Who would like to invite the Grinch to the Whoville annual celebration. She is smart enough to know he won’t come if he isn’t feeling happy. Whoville legend clearly sates that the Grinch is only happy for a period of one hour during each 24 hour period. In addition, the Grinch normally sleeps for about 9 hours each day(from 9:00 at night until 6:00 the following morning. He is never happy while he is sleeping!! Can you help Cindy Lou Who find the best time to climb Mt. Crumpit and invite him to the celebration?

The Following Graph lists the rate at which the Grinch’s mood is changing over a period

of 24 hours.

1.) What would be the best time that Cindy Lou should knock on the Grinch’s door?

Explain.

1.) At 9:00 in the morning, so between 1.) At 9:00 in the morning, so between 8:30 am and 9:30 am because the graph 8:30 am and 9:30 am because the graph

has the most positive area here.has the most positive area here.

2.) For some mathematical fun, 2.) For some mathematical fun, when is the graph of the Grinch’s when is the graph of the Grinch’s

mood concave up?mood concave up?

2.) We drew the derivative, and found

that it was concave up at (13.5,21] or 1:30 to 9.

3.) Can we determine the numerical value of his mood at any time

during the day? Explain.

3.) No, because you can not determine his mood when he is

sleeping silly heads!
