I find it a bit paradoxical that those articles that aim to make calculus more approachable to everyday people are always assuming that those very people already know what the Sigma symbol means, or what [that](http://juliendesrosiers.ca/uploaded/weird-math-symbol.png http://juliendesrosiers.ca/uploaded/weird-math-symbol.png) math symbol means. I see the author in this case is defining the delta and approximately-equal symbols, but I see quite a few non-obvious symbols in this article.
Maybe it's because I'm canadian or that I have not studied advanced mathematics in high-school?
- nso95 8y agoSeems to assume an understanding of precalculus or advanced algebra 2
- Diobo1000 8y agoI'm in highschool in Canada and can confirm that we have covered both of those symbols.
- juliend2 8y agoThanks for the confirmation. Maybe it's just that I don't remember. Or maybe it's that I was in an advanced math class.
- sincerely 8y agoI graduated Ontario high school in the last decade and grade 12 calculus (required for many university programs) covers both.
- mcbits 8y agoThere is a footnote on page 10 that briefly explains both of those symbols, although I doubt many people would immediately understand the footnote if they weren't already familiar with the symbols and concepts.
