Taking a math prep for college sometime next month. However, I have rusted in some areas and want to do some reviewing. What would the anons here suggest?
Studying general metric and topological spaces is one I'd suggest.
The result he's referring to is only really a suprise depending on the way you define the exponential and trigonometric functions and derive their properties.
It's a pretty obvious fact when you do it a certain way.
General topological spaces tie in calculus and geometry and algebra and a whole host of other things in a really beautiful way.
