My Prof wants the Integral to 20 decimal places. where do I specify that with NIntegrate? NIntegrate[f[x],{x,0,3}] Thanks in advance
Sounds like something which you could achieve by setting the "PrecisionGoal->" option for NIntegrate (if it's otherwise attainable). http://reference.wolfram.com/mathematica/guide/Mathematica.html?docs has more.
