Math, Santa, and Venn Diagrams

It’s nearly Christmas, so I’d like to have some rest and avoid serious math posts. To be honest, I’m really thinking about the costume that I’m going to wear tomorrow for our Any Costume Christmas party. I’m thinking about a Dragon Ball Z costume (Vegeta perhaps?). I suppose we have the same height (lol).

Anyway, I found a Venn diagram (see, it’s still related to math), with Santa on the intersection. You would probably agree with me that the one who thought about this is a genius.

By the way, a Venn diagram is a schematic diagram that show logical relations between sets (sorry can’t help it). Venn diagrams are used in elementary set theory especially to represent set relationships in probability, logic, statistics, and computer science.

Plot Functions with Google Search

Google has recently added a graphing functionality to its search engine. You can now plot functions in Google’s search engine as shown below.  The graphs can be panned and zoomed.
You can also graph multiple functions using commas.  The graphs above were generated by typing x^2, x, sin(x), ln(x) in the search engine. Google is capable of graphing single variable functions including trigonometric, exponential, and logarithmic functions as well as their compositions.
