Graphing Problem - Can't graph piece wise function -SOLVED - Сообщения
#1 Опубликовано: 03.10.2017 23:38:03
I've tried many ways from examples I have found on the internet, but I just can't get the graph to plot. What am I doing wrong?
Any help would be greatly appreciated.
[b]Foot note:
The problems are solved. The main problem was units; units must be correct through out. When using constants be sure the value also has units attached (1.5 m, not 1.5, for example). The second was that for the extended graph plugin there seems to be a limit on the levels of conditional functions you can call. I ended writing the function as a one line which worked:

m(x)={((x≥0m)&(x

Hello Dave,
maybe a simple scaling problem? Your results are of magnitude 8 N, your plot is in [kN].
Try scaling the plot area with [Ctrl]+scroll wheel or [Shift]+ scroll wheel.
Hope this helps...

Input units are needed... in the standard 2D plot, just use p(x*'m) / V(x*'m)
