How do I correctly use the SOLVE() function in Python?

[parisse]

The CAS library is named cas, not linalg (which is for linear algebra).

Code:


from cas import *
caseval("solve(2x+8=0,x)")

caseval (or xcas) takes a string as argument and returns a string. It can also take a string containing the commandname, and several arguments (maximum 7). These arguments will be printed to a string (unless they are already strings) and appended to the commandname string with "(" and "," and ")" added. Example:

Code:


from cas import *
x="x"
xcas("solve","2x+8=0",x)
