The answer to d) i) is in the other thread.

It is working.

WorkingPrecision did not work?

Ah, there it is. I found the AccuracyGoal and PrecisionGoal, but they didn't help.
Thanks!

Easy, use WorkingPrecision-> some number.

Hi bobbym
How do I get more accuracy out of NIntegrate?

Here is more:
http://maxima.sourceforge.net/documentation.html
I got
romberg(1/(cos(x)+x^2), x, 0, 100);
1.828017700397752
which is accurate. By setting rombergit to 200 and rombergtol to 1E-10.
Now you need to get a bfloat in there somehow.

I get 0.66666657420034.
Thanks for the links. I will try 'em out.

Set it 25. and rombergtol: 1.e-6, what happens?
You should know about these:
http://eagle.cs.kent.edu/MAXIMA/maxima_21.html
http://www.csulb.edu/~woollett/
get them if you do not.

It is 11.

There should be a global variable called rombergit. What is its value?
- anonimnystefy
- 2013-03-05 06:22:55
It is working and giving out: 0.66653268137515

Try adjusting rombergtol: 1.e-3
- anonimnystefy
- 2013-03-05 06:19:48
It says "Romberg failed to converge".

Hmmm? Change that exp(-x) to sqrt(x) and change f(0,50 ) to f(0,1)
