Hey there Ispom!
You've inspired me to have a play and learn to do some of this in mathcad!
Here's some of my humble first attempts...
My attempts are a bit hit and miss at the moment, as all my maths and engineering books are packed away so I don't have much reference material readily to hand to pick out interesting functions.
Never mind - at least I'm playing with mathcad, and after we move and I can set my office up again I'll be away!
