Mupad can do partial derivatives as well
It can also do definite integrals
Try the integral without the ‘assume(‘σ’>0) as well (just say delete(‘σ’) and do the integral
again – you get a big mess). Notice also that Mupad interprets log(x) to be the natural log – this is
standard practice in math and engineering (log

very rarely comes up except in signal processing e.g. to
define things like decibels).
