Has anybody encountered the same problems with solving integrals in Ver. 9 as I did? Here a very simple example: Integrate[D[f[x], x] / f[x], {x, 0, T}] Version 8.04 gives the correct results: -Log[f[0]] + Log[f[T]] In Version 9.00 as well as 9.01 this integral can't be solved. With more complicated integrals I had the same problems. Version 8 gives a solution, Version 9 doesn't! Could some other Version 9 users try it.
