# NIntegrate::inumr error, but only for some values.

Posted 10 years ago
 Hello,I am having trouble getting a double integral to work. It is a function of k, and works well for one value of k (k=2)that I can find. Any other value, and the function spits out this error message:NIntegrate::inumr: The integrand Re[\!$$\*SubsuperscriptBox[\(\$$, $$-1.13$$, $$50$$]$$\(0.000035237548017848564\ \*SuperscriptBox[\(E$$, $$\(-t$$\ $$(\(\(0.02$$\) + Times[<<2>>])\) - 0.039241305112179804\ Re + 0.039241305112179804\ \*SuperscriptBox[$$2$$, $$Times[<<2>>]$$]\ Re\)]\ Re[\*SuperscriptBox[$$E$$, $$\(-0.2092315267335341$$\ \*SuperscriptBox[$$Abs[<<1>>]$$, $$2.01`$$]\)]]\) \T\)\)] has evaluated to non-numerical values for all sampling points in the region with boundaries {{0,500}}. >>Here is the function:ginfinity[\_] := Re[NIntegrate[minfinity[\, t], {t, 0, 500}]]whereminfinity[\_, t_] := Re[Integrate[ E^(\[T, t] - ((\[T, t]) (t)) - \[T, t] (1/2)^(t/ H)) (zta[\, T]) .000136, {T, thetat, 50}]]If anybody has any idea of what could be going wrong, I would greatly appreciate it!Thank you,Katherine
