1. Math tip (a) – Graphs using free math software
The latest IntMath Poll asked readers how they normally draw math graphs.
The response from 1900 users was interesting:
65% said they use paper; 20% said graphics calculator and 15% said computer software.
There are many free online and downloadable graphics programs out there and it surprises me so few people use them to draw their math graphs.
In this tip, I show how to avoid some of the pitfalls of using software to draw graphs. Go to:
Graphs using free math software
2. Math tip (b) – Math of drugs and bodies (pharmacokinetics)
Several people have written asking me to write an introduction to pharmacokinetics. This is the process where the body absorbs and metabolizes drugs (or food, or any chemical).
The math involves diffrential equations, but I think everyone will find it an interesting read. Go to:

3. Latest IntMath Poll - Math applications
One of the most common questions from math students is, "When are we ever going to use this stuff?"
This month's IntMath Poll asks readers whether they feel they get a good understanding of how math is applied in the "real world".

5. Final thoughts
a. Practice
Everyone tells us to practice math and you will become an expert. Here's another take on that advice.
Practice does not make perfect.

b. Biodiversity
2010 is the International Year of Biodiversity. The rise and decline of populations is a very interesting math topic.
What can you do to study - and help - endangered species in your area?
Until next time, enjoy whatever you learn.

Intmath Newsletter is so educative, I dont know how I would cope without it at the moment. I will always read it and apply the concepts in my everyday situations. Please keep up the good work you are doing, the masses are benefiting from it.
