Integrate Sqrt[ ex1].I havent tried it, but thats what I would start with since the ordinary substitutions dont seem to lead anywhere and integration by parts also seems to be a dead Can you tell me please how much is : (x ln x) ? Oana, The derivative of ln(x) is 1/x so if you try integration by parts with u ln(x) then the resulting integrand will not contain a log function but only powers of x. Integration by Parts is a special method of integration that is often useful when two functions are multiplied together, but is also helpful in other ways.Differentiate u: ln(x) 1/x. Integrate "sqrt x ln x"?
