Which numerical integration method is best to use for an arbitary function of which nothing is known?
Currently I'm using "Simpson's rule", something I found using google. I found something called the "Romberg method" too, but I was unable to find its implementation.
"Simpson's rule" seems quite OK, though.
Secondly, when you are writing math formulas using ascii, how do you write integrals?
Examples:
Code:integrate(f, a,b)
integral{a,b}(f)
§[a,b] f(x)
