Is it possible to differentiate the following equation, if so could you please explain. S=SQRT(T(5/X^2)) I would like the derivative of S with respect to X. I have had a go at this myself and arrived at the 5/(x^2*(sqrt(t*x^25)) Regards David 

Hi David, I think some symbols didn't survive through the email so let me make sure I have the correct problem. You want the partial derivative of S with respect to x where Using the chain rule I get or Harley
