Hi,
How to turn of the decimal values in trygonometry angles value? I got sth lik this for solution of system of equations:

You can use the function al_nlegsolve with any initial
assumptions (because the equations are linear)

By default, trig are in decimal radian in all CAS.
Recast your solutions, fill-in the unit place holder.

Hi. You also can use Maxima commands, in this case ev():

Hi Martin. I use Maxima's ev() because SMath's Assign() only works with the variable names, instead others, like xo, yo, and SMath's at() doesn't works for the symbolic evaluation, as shown this picture:

This is a workaround for use only SMath native functions or plugins, without any explicit Maxima function:

example_v2.sm (15 KiB) downloaded 23 time(s).

Best regards.
Alvaro.
