Dear Geometry B class,

Do not submit until AFTER you are finished with the practice final.

Here’s the link to the practice final:

I wrote a tutorial for interacting with GeoGebra applets using JavaScript. I wrote it for Windows users. You can read it below.

I wrote about the Common Core State Standards for Mathematics in the “CA CCSSM” section of MathwithJoy. I am currently working on “roadmaps” for each class that I may teach in the future.

I will also fix the “Card Dealer” and “Bouncing Ball” applications when I get the chance. I am looking for my RSA cryptosystem application; if I can’t find it, I might have to rewrite it. I am currently working on my first GeoGebra/Javascript application inspired by the CCSSM Workshop that I attended at CSUN this past weekend. The presenter at the workshop was Heather Dallas, Executive Director, UCLA Philip C. Curtis Jr. Center for Mathematics and Teaching.

There is a tutorial (link) online on creating a clone of the arcade game “Breakout.” I decided to modify it; I was hoping that - in the process – I would learn more about using Javascript and the <canvas> element as well as creating a web application that could help Algebra 1 students explore the concept of slope.

Please note that I developed this application for fun and that it is not meant for commercial, business, or professional use.

I developed a web application that deals cards. I think this application may be useful in mathematics classrooms for activities requiring a deck of cards. I still have to work out a couple of bugs and clean up the code.

Here’s the link: http://mathwithjoy.com/apps/carddealer/carddealer.html.

Credit for the card images and some of the Javascript code (for constructing and shuffling a deck of cards) goes to Michael Moncor who wrote “Sams Teach Yourself Javascript in 24 Hours.” This is an excellent book. Click on this link to the book’s webpage on the publisher’s website for more information.

I looked at algorithms (available all over the internet) for shuffling a deck of cards and they all seem to do the following: pick two random cards in the deck, switch their order, and repeat many times.

I developed a web application that will encrypt a message given the enciphering modulus and the public key . must be a positive integer that is a product of two very large and distinct primes ( and ) and must be a positive integer such that , .

The web application will calculate the private key by solving the congruence .

The web application can also decrypt a message given the private key and the enciphering modulus .

I developed a web application that calculates the real root of a cubic equation for one of the classes I’m taking at CSUN.

Here’s the link: http://mathwithjoy.com/apps/cubic/cubic.htm.

Given a cubic equation of the form , the web application calculates the coefficient of the first-degree term and the constant of the depressed cubic equation that is the result of substituting in for .

The web application then calculates and ().

The web application then calculates the real root of the cubic equation.

There are fields below the value of on the web application. These are for the other two roots of the cubic equation. I have not finished writing the code for this yet. I also have to figure out how to non-real numbers in the calculations.

I just finished developing the structure for a web application I call “My Math Notes” that will contain basic mathematical concepts and definitions for classes I’ve taken at CSUN. This web application is optimized for mobile operating systems like iOS and Android.

The link is http://www.mathwithjoy.com/apps/mymathnotes/.

Whenever I add an entry related to a math class I’m taking or have taken, I will add a link to that entry in the web application.

I developed a web application (“Wheel”) that calculates pro rate and short rate factors. The web application is optimized for mobile operating systems like iOS and Android.

Here’s the link: http://www.mathwithjoy.com/apps/wheel/wheel.htm.

Please note that I cannot guarantee the accuracy of the results of this application. I just developed it for fun, not for actual business use.
