Hi, I've been using gfortran on windows through the command line to compile .f95 files using the command gfortran file.f95 to get an a.exe file which I can then run. However, I'm currently writing some Fortran code which needs some of the subroutines of the LAPACK package. I've been...

Thanks very much for your response but, to use your example, suppose the original differential equation is y' / y^2 = 1 instead of y' = y^2 what I'm wanting to find out is why the rearranged solution of y' / y^2 doesn't seem to go through the singular point of 1 / y^2 Thanks

Hi, The final step of solving a separable ODE is to find a function, f, defined implicitly by a relation G(y) = H(x). Say G(y) isn't defined at y = a and H(x) isn't defined at x = b, it appears to me that when rearranging such a relation to put y in terms of x, the point at which G(y) isn't...

Again, as far as i know, In the first situation where the gas is cooled, it can't maintain its volume but the container maintains the same volume (because we assume it's rigid). By allowing the walls of the container to move, the wall(s) impart kinetic energy to the particles (because they are...

From the little I know, The idea of the enthalpy is that you can consider a system as having some energy by virtue of it existing in a volume V at a pressure p. The extra amount of energy that it is considered to have is equal to pV. Take, for example, a perfect gas. Say a perfect gas occupies...
