Prime Diophantine Equations

</roll>

OK, so I know what Diophantine equations are. They are polynomial equations with only integer solutions. An example:

2*x* + 5*y* = 2,

which has integer solution

(-3,1).

The *Prime *Diophantine Equations are a set of 14 polynomials that generate prime numbers!

So that is cool!

And as for “Diophantine”:

Diophantus of Alexandria was an awesome mathematician who wrote the book on arithmetic! No, seriously: his book is called *Arithmetica*! And here’s a little puzzle about his life from the 5th century:

“*Here lies Diophantus.**God gave him his boyhood one-sixth of his life;**One twelfth more as youth while whiskers grew rife;**And then yet one-seventh ‘ere marriage begun.**In five years there came a bouncing new son;**Alas, the dear child of master and sage,**After attaining half the measure of his father’s life, chill fate took him.**After consoling his fate by the science of numbers for four years, he ended his life.*”

How old was he when he died?

## Updates

**UW Math Placement***Last updated 5/12/2020*

Just in from the UW Math Department, some answers to your questions:

Q) *Are there any math problems I’ll need to solve on the new assessment?*

A) Yes, there are still math problems students will solve. We give instructions, which mimic a midterm exam test for us, so the student should take it seriously. They will check their own work to see if they got the problem correct.

Q)* Do I need to take the assessment if I completed AP Calculus? Running Start Precalculus? Running Start Calculus? IB Math?*

A) All of our previous AP, running start and IB policies are still in place. In fact, this new process does not give a student the ability to bypass Math 124. So if a student earned credit for Math 124 through AP or running start, then they can take Math 125. If a student earned credit for MATH 098 or MATH 120, we would still encourage them to take the GSP since it is available but they could also just register for the next course they think they are ready to take.

Q) *If I do not NEED to take the test, should I take it anyway?*

A) All students in MATH 111, MATH 120 or MATH 124 will be asked to take the GSP. Some faculty will likely have their first homework or quiz be similar to the GSP assessment. So it is important that students take the GSP and have a good understanding of their mathematical foundation when entering the course. Maybe they take the GSP and realize they need to work on their understanding of trigonometry even though they took pre-calc/trig. We will provide a review materials website that helps students refresh their math skills before the quarter begins.

**AP Calculus***Last updated 5/30/2020*

If you will be taking a makeup AP exam in June, please contact us! We can help!

Also, log in to your College Board account to ensure you’re registered for the test. PLEASE contact us and your school if you have ANY questions!

## Math Is Fun.

*Updated 23 September 2020*

One day a farmer called up an engineer, a physicist, and a mathematician and asked them to fence of the largest possible area with the least amount of fence.

The engineer made the fence in a circle and proclaimed that he had the most efficient design.

The physicist made a long, straight line and proclaimed “We can assume the length is infinite…” and pointed out that fencing off half of the Earth was certainly a more efficient way to do it.

The Mathematician just laughed at them. She built a tiny fence around herself and said “I declare myself to be on the outside.”
