I'm pretty sure Calc courses aren't required for college in the US. I think everything from trig up is usually offered at a college. Probably shouldn't expect to get in anywhere good if you haven't taken extra maths in highschool, though. At least not if you're majoring in an engineering or science discipline.
I don't think I've ever used Euler notation.
