I <3 Google Graphs

April 11th, 2012 No comments

I’ve only just found out that Google does graphs. These at least, appear to be working better than Google Translate, and Google Calculator.

Go to and paste the following into the search:

(sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01, sqrt(9-x^2), -sqrt(9-x^2) from -4.5 to 4.5

Happy π (Pi) Day!

Pi Pie

Pi Day is a holiday commemorating the mathematical constant π (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form.

Pi Approximation Day is held on July 22 (or 22/7 in day/month date format), since the fraction 22⁄7 is a common approximation of π.
