A custom Maxima Riemann sum functionCode:integraten(f,a,b,n):=sum(ev(f,x=a+i*(ba)/n)*(ba)/n,i,0,n1); Last edited by anonimnystefy (20130419 10:13:46) The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #2 20120825 07:00:01
Re: A custom Maxima Riemann sum functionHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20120825 07:02:56
Re: A custom Maxima Riemann sum functionev(expresson in x, x=value) evaluates the expression at a specified value of the variable x (or any variable which the expression is given with).

Re: A custom Maxima Riemann sum functionHi anonimnystefy; Code:s:s+ev(f,x=i)*(ab)/n, In mathematics, you don't understand things. You just get used to them.

Re: A custom Maxima Riemann sum functionOh yeah. It should be ba there.
