| Oct 10, 2016 at 5:05 | comment | added | Engine_ear | I added the full context of the problem that I should've had upfront when posing the question earlier. | |

I added the context that I should have had upfront with posing the original question.

Best solution is to use a numerical table like that of an error function in probability theory unless you can solve it analytically. | |
| Oct 9, 2016 at 7:30 | comment | added | Matt L. | You should give us more context. It looks like you're trying to solve for the 90% bandwidth of some system. Could you add the actual question that leads to that integral? | |

| Oct 9, 2016 at 3:53 | comment | added | msm | You also need to define $\text{sinc}(x)$ since it has two definitions. If it is $\frac{\sin(\pi x)}{\pi x}$, then there is no answer because $$\int_{0}^{\infty}\text{sinc}^2(x/2)dx=1$$ which is less than $0.9(\pi)$. Are you sure there is a $1/\pi$? | |
