The Map of Mathematics — Infographic

The Map of Mathematics

When are we going to use this?  Why do we learn this?  How much math is really out there?  This interesting map of mathematics was created to show just how wide reaching and diverse the field of mathematics really can be.  From learning to count to simple arithmetic into more advanced areas like calculus and differential geometry to practical applications like statistics, game theory and even economics, this chart has it all.  Make sure to check out the wonderful video explaining it all, linked below.   [VIA]

MyScript Calculator – Intuitive Handwritten Math App

MyScript Calculator

This is my new favorite app!  The MyScript Calculator is a unique tool that allows students to handwrite complex equations and formulas into their iPad or iPhone and obtain instant results.  Not only can this be used to perform simple arithmetic operations, but the MyScript Calculator can also handle more complex operations, including trigonometric functions, logarithms, and certain constant expressions.

From the developer, the full list of supported operators includes:

Basic operations: +, -, x, ÷, +/, 1/x
Misc. Operations: %, √, x!, |x|
Powers/Exponentials:
x, xy , x2
Brackets: ( )
Trigonometry: cos, sin, tan
Inverse trigonometry: acos, asin, atan
Logarithms: ln , log
Constants: π,
, Phi.

One of the only drawbacks of the MyScript Calculator is that while the technology is intuitive, it is not perfect as assessing what students intend as they write.  Therefore, it is important that they try to do so neatly in the app.  Also, variables are not written as they would in a common algebraic expression.  For example, MyScript reads “x” as multiplication instead of a variable.  Simple single variable expressions can be solved but students need to use “?” as that variable, as opposed to letters.

The applications and advantages of this app are enormous, however.  Students who are unable (or unwilling) to use a basic calculator can try MyScript for a more tactile math experience.  This would also be a help to those students who need to solve more complex calculations that would be difficult with pen, paper, and a traditional calculator.  While MyScript will not, and should not, replace more traditional methods of computation and equation solving it is a fantastic tool to have in your belt.

Video of the Day – 3/14/13 (Calculating Pi with Real Pies)

Daily Video — “Calculating Pi with Real Pies”

The gents at Numberphile have outdone themselves again!  Check out this fantastic, fun video where they attempt to calculate the actual value of pi using one of my favorite things — real pies!! 🙂  (Make sure you check out the run-time too, those sneaky buggers!)

Happy Pi Day — Infographic

All You Wanted to Know About Pi

March 14. 3/14. 3.14 Pi Day! Today is the day that the math teachers in my building live for, and there is a full slate of activities planned in all their classes. How much do we really know about pi, however? I know I am still caught in the trap that when I hear the word, all I can think of are delicious circles of Apple or Coconutty goodness — which makes me half right, I suppose! Today’s infographic helps to explain some of the properties of pi, as well as its many applications in mathematics and engineering. [VIA]
