thanks for your help. this was a simplification of a Navier Stokes equation but I am having problem simplifying the equation after integration... original Integral Q = \int^{ro}_{ri} [r^{2} - ro^{2} + \frac{ri^{2} - ro^{2}}{ln(ro/ri)}ln\frac{r}{ro}]rdr where ro and ri are constants...

u = ln(x/b) => du/dx = 1/xb (is that right ?) dv = x dx => v = (x^2)/2 using formula... \frac{x^2}{2}Ln(x/b) - \int (x^2)/2xb how would you integrate this step ?

I have tried quite a few methods but haven't solved this problem, any help ? \oint axLn(x/b) dx where a and b are constants I have tried moving the 'a' outside the integration and solving xln(x/b) using integration by parts . I have also tried splitting xln(x/b) into xlnx -xlnb and...

very eventfull race, but a very stupid mistake from hamilton. Hamilton and Rosberg get a 10 place grid penalty for the french gp

how about \Gamma(0) I read somewhere that its a complex infinity but don't understand what that means

thanks for your help

yeah the original integral was \int[0,4]Y^{3/2}(16-Y^{2})^{1/2} dy which i simplified to 64\int(0,1) t^{(5/4)-1}(1-t)^{(3/2)-1} dt using Gamma(x)=int(0,oo)tx-1e-tdt, =>> \beta(5/4, 3/2)hence i am trying to solve \beta(5/4, 3/2) = \Gamma(5/4)\Gamma(3/2) / \Gamma((5/2)+(3/2)) i am trying to...

I'am not sure how to solve this gamma function \Gamma(5/4). any help ? sorry if this is in the wrong section.
