Hi there,
is it possible to get exact point of functions intersection in Smath somehow? I have simply linear and constant function.
BR,
Marcin

There are more opportunities: without the use of plugins, for example, you can use the function or the method of inversion of the matrix. sergio

The method 2, of course, no; the method 1 yes, but get only one solution.
You can also use the internal function, "solve", or the plugins.
Search on the forum the plugins "nonlinearsolvers" and "maxima". Allow to extend the solution of nonlinear equations (reading the discussions can also highlight some limitations highlighted by users).

Read the first example carefully. 'solve' is inaccurate on long range but the initial is good enough to reduce the brackets. Wise to check with accurate 'Dichotomy'. Jean  Forum Solve.sm (16kb) downloaded 41 time(s).

"roots" is a great solving companion: solve explicit & solve general intersection. Jean Solve roots.sm (13kb) downloaded 51 time(s).
