M3/C4 Integration help

hi,

I'm doing question 6 in the June 09 M3 paper and am having some integration difficulties because I haven't covered C4 fully yet.

How is it best to integrate: ( 10000v2 ) / ( 8000-v3 )

Thanks,

Use the substitution u=8000−v3u = 8000-v^3, or if you're not comfortable with substitutions, try to see how the expression in the numerator is related to the expression in the denominator.
