Re: How hard is college level mathematics?

I don' t know where everyone is from. But here, intro calc typically has very low grade averages. Whereas people who are mathematically inclined find it very easy, the general population does not and it's one of the reasons there are tons of jobs for tutoring it. In my grade 12th year we didn't even...

To add to Taliths post, you're not the first person to be uncomfortable with irrational numbers. \sqrt{2} is a better example than \pi because it was proved to be an irrational number first, and the proof is easier to understand and doesn't involve calculus. Early Greek mathematicians were quasi-rel...
