The Math Tutor: Simplifying Probability

Posted by Eriene Sidhom on 3/2/15 12:08 PM

Dungeons and Dragons is complicated. Mastering probability doesn’t have to be.

Probability is one of those topics that haunt children from grade school days of the determining the likelihood of picking out red marbles from a box. Even my most advanced math tutoring students in Cambridge sometimes feel bamboozled by it. Why? Because probability and statistics can quickly become overwhelming with the many different distributions and definitions.  The key is to find the underlying patterns and to stay organized.

The Math Tutor: 3 Anecdotes from Great Mathematicians’ Lives

Posted by Eriene Sidhom on 1/16/15 11:30 AM

It’s a shame that so many people can go through college as math majors and minors without ever learning the history of mathematics. Who were Euler and Gauss? Newton and Leibnitz? Euclid? We all know their theorems and mathematical contributions, but rarely do most of us think of the people —with their messy lives, quirks, and stories— behind these brilliant minds. Understanding these lives can provide context to learning math at a whole new level.

Even as an advanced math tutor in Boston and a student at MIT, I am guilty of this myself. But since it’s the time for making New Years resolutions, I’ll make one of mine to learn more about the people behind the incredible mathematical discoveries. Today, I’ll share three of my favorite mathematical anecdotes:

Math Tutor: 4 Easy Steps to Volume Rotation Integration

Posted by Eriene Sidhom on 12/24/14 10:00 AM

Merry Christmas Eve! Why yes, I do believe volume rotation integration is as easy as apple pie! 


Every once in a while something you learn in class really just knocks you off your feet. Those of you who have taken AP physics will know that position is the integral of velocity. About a month ago, on a fairly dreary Boston morning, I was sitting in my neurobiology class, semi-interested, when the professor informed us off something truly shocking: our brain determines and maintains our eye position by literally integrating velocity information into position information. 

It took humanity all the way until Newton and Leibnitz to figure out calculus, and it takes the education system about twelve years to teach calculus. All the while you are subconsciously integrating every second that you are awake.  So while it is completely understandable that AP Calculus can be intimidating, it’s at least somewhat comforting to know that you—or at least your eyeballs—have been doing it your entire life!

Unfortunately, as a math tutor near MIT, I’ve found that even for ambitious students,  doing calculus is much more difficult. So here are 4 easy steps to remember when doing those pesky volume rotation integration problems.
