Math Site

Someone dropped a link to his math site a while ago, and I haven’t really gotten the time to update, but here goes.

Mastering Maths Smartly, he calls it. Step-by-steps on how to solve your typical math problems, plus some practices as well. Cool stuff.

P&C Crashcourse

Okay, so it’s not really a crashcourse, but I had a lot of people asking me how to tackle P&C questions over the past few months – notwithstanding the fact that I used to have problems with P&C as well - so here is a list of questions, with worked solutions that you’ll hopefully find useful in helping you understand P&C.

You might also want to check out the H2 Mathematics Applets page I linked a while ago, under Permutations & Combinations for applets that might be useful in helping you with various P&C problems.

Math Sites

John von Neumann once said, “Young man, in mathematics you don’t understand things. You just get used to them.” But that has nothing to do with this post, apart from the fact that it’s about math, and one of history’s greatest mathematicians said that. Anyway, the following sites are great.

1. H2 Mathematics Applets
If we took everything at face value we’d probably be screwed. This site is awesome if not painful on the eyes. If your concepts are a bit weak, these applets would probably help you visualize things with a bit more ease.

2. MathWorld
Everything you would practically (and impractically) need to know for math can probably be found here.

3. The Integrator
Three guesses what it does. (Input takes some getting used to though.)

4. Calc101.com
Alright this site does a whole lot of stuff. It’s best you explore yourself. Some functions need a paid password, though.

Much thanks to the RJC Math Department for these links
