Homework Statement
Ok, this is not really a problem, but I need help on understanding the basics of sin, cos, tan, and their inverses.
i was looking at http://www.analyzemath.com/DomainRange/domain_range_functions.html and it was saying that the domain for sin and cos is (-inf , + inf)
and then for tan it is All real numbers
except pi/1 + n*Pi
but then for csc, it is All real numbers
except n*Pi
Can you explain why? I think I'm having trouble with figuring out how to find domains and I want to understand this before I start calculus. Please explain.
