Simultaneous Equations

Posted on 2008-12-04 14:17 By noels (1)

Hi all,

I have little (almost zero) experience with Maple. Nonetheless I wish to use Maple 8 to solve a set of 5 equations for 8 unknowns.

At the moment my strategy is to input each equation, make a set of the 5 equations, and then use the 'solve' command to determine the variables. I then refine the answer using 'allvalues' and 'evalf'. Is this the best approach?

Any help or guidance on this is greatly appreciated.

That depends

A general system of 5 equations with 8 unknowns has 3-dimensional variety of solutions, infinite number of them, so such an approach with allvalues and evalf may be not appropriate. It is hard to tell without seeing the system.

There are better methods for some classes of systems, such as systems of linear equations, for example.
