The above series is NOT infinite. There is no such thing as an infinite series. Everything I need to know about the series is contained in the first three terms. :-) Nothing infinite about it!
So is sin(x) defined to be x - x^3/3! + x^5/5! ? Or is the equation sin(x) = x - x^3/3! + x^5/5! proved? If the latter, what is the definition of sin?
