Question: Performing numerical integration (quickly)

Hi,

I'm having problems with numerical integration in maple.

I've integrals of this kind

 

Int(6.989220000*10^12*f^(57/50)/(1.936774504*10^19+2.094942676*10^14*f^2-9.877129764*10^14*f^(107/50)+4.636748856*10^11*f^(207/50)-1.0261950*10^7*f^(307/50)+111.*f^(407/50)), f= 10...1000)

and Maple needs ages to give me a numerical answer (with value(%) ) . Am I doing something odd or it is a "normal" computing time?

I'm running maple in a 8GB RAM, 3Ghz quad core computer

 

Thanks

S.V.
