Well thank you, glad if I could help. There are some other tricks to remember as well. Here is list of which come to my mind at this instant; - symbolic/numeric optimization
most errors can be parsed with selecting the right one
- Δ temperatures (Δ°C, Δ°F, Δ°Re)
- not using units for some solvers {solve(), roots()}
or using multiplications at right place to trick solver as value is unitless
- using maple() or maxima() for most symbolic results (better support)
- smath vectors/matrices starts with 1, mathcad starts with 0
some new users troubles with converting mathcad functions to smath
- recursive functions shall give an error after 50 steps
better not to use it, try to wrtie algorithms conventional way
- eval() for faster calculations
- line() for functions (not needed always)
- to be careful for variable names
- choosing right plot for the right job
Interesting list and I like the explanation of "LINE". In addition, it took me a bit to understand using # in the variable name when I first started. I now use it all the time, but it took me a bit for it to sink in & a newbie needs to understand that it's a special character (I tend to use # first). As I update some of my calculations, I'll look at both of these items

Download 2022 Samples ... see color(M). The algo style I offered previously was not possible official SS 5346, but possible from Un-Official SS 5346 from recollection. Then came superb native Smath 6179. Cheers ... Jean

(swh) Line explanation is not mine, it is from Reference Book. I do started to use some special characters too. This is much easier to assign unique variable names at first than maintaining after using them.
