Hello
I'm trying to do this...
NIntegrate[2 Sec[3 x]^2, {x, 0, 1}]
...but I get an error message:
Integrate::idiv: Integral of Sec[3 x]^2 does not converge on {0,1}. >>
NIntegrate::ncvb: NIntegrate failed to converge to prescribed accuracy after 9 recursive bisections in x near {x} = {0.525375}. NIntegrate obtained 14640.304457539936` and 1500.4844985527366` for the integral and error estimates. >>
NIntegrate[2 Sec[x]^2, {x, 0, 1}] works fine.
Does anyone know what I need to change so I don't get the error message? I've done some searching, but I don't really know what I'm searching for.
I would very much appreciate any help.
Thanks
