MathJournal 2.0 winners announced

What  a great contest! We received a steady stream of entries up until 11:50PM last night and almost all of them were correct. It looks like many of you took the opportunity to review the demo videos and agree with us that Math Journal 2 is an awesome application.

The correct answers were:


Rand (4) = [ -0.6 0.8 -0.7 0.7

                  -0.7 -0.2 -0.2  1

                  0.3 -0.4  0.9 -0.9


                  0.2  -0.8 -0.6 -0.9]



We also accepted .7 since all appearances on the video indicated that .7 was the final solution. The answer we were looking for in exporting data was PowerPoint.


In addition to sending in the correct answers, we decided to award the MathJournal 2.0 license to the first person who sent in their answer in Ink. The consolation prize of Calculator went to the second person who sent in their entry in Ink.


So, on to the winners:

Congratulations to Bryan Pollack who won the Math Journal 2 license, and to Mark Petzold who won the Calculator license.

Special thanks to the anonymous donor who donated the license of Math Journal 2 to give away and to xThink for donating the license of Calculator.

Look for another contest this week…..
