Hello all,

What is that mean? and should I care about it?

I have the following error while the command

**NIntegrate**is executed in*Mathematica*:
Code:

```
NIntegrate::slwcon: Numerical integration converging too slowly; \
suspect one of the following: singularity, value of the integration \
is 0, highly oscillatory integrand, or WorkingPrecision too small. >>
NIntegrate::ncvb: NIntegrate failed to converge to prescribed \
accuracy after 9 recursive bisections in y near {y} = {1.5301}. \
NIntegrate obtained 2.817606086983439`*^-17 and \
5.338249419658235`*^-23 for the integral and error estimates. >>
