One-stop-shop for Ontario Math Education Resources
EduGains Math has released the April 2015 issue of the newsletter Math in Motion. It includes an announcement regarding an online site OntarioMathEdResources.ca that brings together into one place “the comprehensive collection of resources developed or licensed by the Ontario Ministry of Education to support student learning in mathematics”. And, the newsletter says that it will become available as a free app sometime in the Spring 2015.
Totally check this out!

Students to present Mathematics Seminars
The Grand Rapids Community College Mathematics Department is very pleased to announce that it will host two Mathematics Seminars in April, both to be presented by current GRCC students.
Our first talk: Wednesday, April 15, 3:30-4:30 PM in 102 Cook.
Gregory Metzner will discuss applications of Trigonometry related to his experience while serving in the United States Marine Corps. The title and abstract of his talk are below.
This talk will focus on using trigonometry to locate positions on a map, and should appeal to anyone with an interest in real-world applications of mathematics. Familiarity with basic trigonometry would be useful, but of course everyone is welcome!
Pop and cookies will be served at 3:15 PM.
Trigonometry in the Marine Corps
As a high school student, I did not appreciate math. Upon entering the “real world”, I learned that math is integral and used everywhere, and I found that…

Handbook for mathematical modeling of hydraulic transients in vapor condenser cooling water circuits – PART 2
PART 2 – APPENDIX ON A MASS-OSCILLATION MODE FOR CONDENSER COOLING WATER CIRCUITS
This handbook aims to describe the basic physical reality of the subject transients, as well as to make available the equations used for the numerical simulation of the time evolution of the main parameters of interest of a user-defined transient. Standard procedures of time-domain numerical integration can then be used to obtain the desired computer-generated simulations. The latter can be a useful tool for engineering forecasts of the expected behavior of industrial circuits, with particular focus on the cooling water circuits of the vapor condensers of large thermoelectric generating units.
The document herein presented is a synthesis of the joint research carried out by a Working Group of the International Association for Hydraulic Research (IAHR) during about 20 years of activity.

The Humans by Matt Haig
For the first time in a long time, I was part of a book club to read this book. I had heard good things about it but never thought that I would love it as much as I actually did. As we started our reading, I figured I would read it at a steady pace so to not go too far ahead of my friends. But once it came to a certain part in the book, I was obsessed, I needed to finish it as soon as possible.
The Humans by Matt Haig is a story about a mathematician named Andrew Martin who solves one of the world’s most challenging math theories. The theory was so advanced that it caught the attention of alien life forms who then decided that it would be too much for the human race to handle. So they decide to take Andrew from his home…

10 Calculator Buttons you need in your life #revision #gcse #alevel
Before we start, let me get one thing out of the way – you will only get so far without showing your working. Nevertheless, even a seasoned Maths student needs some calculator skills from time to time. Enjoy.
1. Time conversion between decimal and hours/mins/secs can be tricky. Check your answer with the snazzy ‘commas and dot’ button:
Type your decimal, e.g. 2.4 (hours) press equal then convert with the button below Alpha B.
Your life is now complete.
(As Will Davies rightly pointed out on my earlier post: I use it for time, but this button is actually to convert angles into degrees, minutes and seconds ie fractions of degrees – 60ths and 3600ths)
2. Prime Factorisation
Want to check your product of primes? Or better still, check whether a number is prime?
Simply type your number, press equal then convert with FACT (next to the Alpha B). If…
