J(p)=s: S.A.Tricky
http://jfunctiontutor.blogspot.com/2008/04/satricky.html
Tuesday, April 29, 2008. Here's an S.A.T. problem that stumped my students and me (for a little while). My instincts were to look for a connection between (. But it's really much simpler than that. Solve for. In the first equation, and substitute into the second equation. Edit: The original post contained a mistake. (10. Solved by J Function. Are you sure than answer is right? May 4, 2008 at 10:08 AM. You're right, joe, thanks. That should have been 20b instead of 2b when I expanded the square. Let's exp...

J(p)=s: June 2010
http://jfunctiontutor.blogspot.com/2010_06_01_archive.html
Thursday, June 3, 2010. Suppose Genie walks her dog Hitch on a trail where Hitch can run around without a leash. Genie wants to make sure Hitch gets a certain number of miles of running per day, but she doesn't want to walk that far herself. How long does Genie have to walk to make sure Hitch gets enough running? Solved by J Function. Subscribe to: Posts (Atom). About J(p) = s. Principle of Mathematical Induction.

J(p)=s: April 2010
http://jfunctiontutor.blogspot.com/2010_04_01_archive.html
Thursday, April 15, 2010. Both eukaryotes and bacteria must transcribe the genes in their DNA into RNA transcripts in order to use them. The process starts out much the same in both kinds of organisms. In bacteria, the process is logical and efficient. In eukaryotic organisms like plants, fungi and animals (us), the process has gone hideously awry, and evolution has again employed a sloppy and inefficient fix. Both bacteria and eukaryotes have promoters. Then again maybe there is some wisdom here. Ba...

J(p)=s: March 2008
http://jfunctiontutor.blogspot.com/2008_03_01_archive.html
Monday, March 31, 2008. My friend Justin was reminiscing about some Atari-aged video games: Subspace. The problem they inspired reminds me more of Asteroids. A turret in a video game can rotate but not change location. It shoots bullets that travel with a constant velocity V. An asteroid travels at a constant velocity V. Where should the turret aim to hit the asteroid? For the asteroid at ( x. And add a point for the eventual collision at ( x. Label the distances traveled by the asteroid and the bullet D.

J(p)=s: May 2008
http://jfunctiontutor.blogspot.com/2008_05_01_archive.html
Tuesday, May 6, 2008. After doing the back-stitching on a few of the letters in this counted cross stitch pattern, I wondered if there would always be an even amount of stitches in the outline of a block shape. I will prove that the perimeter is always an even number of units using the Principle of Mathematical Induction. Base case: consider a one-square block shape. Its perimeter is 4 units - one for each side. Since 4 is even, the proposition holds for the base case. Squares has an even perimeter.

J(p)=s: IDEAs
http://jfunctiontutor.blogspot.com/2008/04/ideas.html
Thursday, April 24, 2008. Here's another S.A.T. problem. In the correctly worked addition problem to the left, A. Each represent a different digit. What is the smallest possible value of D. You don't need to know what every digit in the problem is. You only need to know which digits have to be assigned to which letters in order for the addition problem to work. Starting in the one's column, E. The most two one-digit numbers can add to is 18, so the carry digit would have to be 10. If E. The value of A.

J(p)=s: Prime Factorization
http://jfunctiontutor.blogspot.com/2008/04/prime-factorization.html
Thursday, April 10, 2008. This problem comes form Project Euler. I solved it with a computer program written in C . What is the largest prime factor of the number 600851475143? It is tempting to write a function to find the prime factorization of a given number. Why? I wrote that function, too, but I'm only going to cover the process of solving the given problem. I might do something like what I did in the diagram to the right. In words, our algorithm might look something like this:. Divide it by 2.

J(p)=s: Genie and Hitch

Genie wants to make sure Hitch gets a certain number of miles of running per day, but she doesn't want to walk that far herself. How long does Genie have to walk to make sure Hitch gets enough running? Solved by J Function. How long does Genie have to walk to make sure Hitch gets enough running? Not at all. She sits on a bench and repeatedly throws a ball for Hitch to fetch. About J(p) = s.
