Integrating a Interpolation function with domain {0,1} and output dimension >1: I don't unde...
My goal is to integrate the last dimension of the output of an Interpolation function. I am getting behavior that I don't understand (note to readers, I've pasted all the code without comments at the …

Nested usage of NIntegrate
How about this?
nint[x_?NumericQ] :=
NIntegrate[
0.00015*
Exp[-y^2]/(2.21*10^-7 + (((3*10^10)/x - 2.47*10^15)/(1.06*10^11) -
y)^2), {y, -\[Infinity], \[Infinity]}]
e.g.,
nint[.003]

Numerical_integration
Some values of x0 may be giving you integrands that you may not have anticipated. For example:
iEq10[x_, x0_] := (x*Sqrt[((x/x0)^2)*(1 - (1/x0)) - (1 - (1/x))])^(-1)
Note the behavior of the integra …

Issues to compute and plot a function with some Fourier analysis
Here is a a beginning. When I have some more time, I'll come back and edit this.
Second Edit at Bottom, I normalized your distance variable and made your problem symmetric around the origin.
The objec …
