To solve for P

, use the command SOLVE from the S.SLV menu

(„Î), it may take the calculator a minute to produce the result:

{[‘Pi=-(((σθ-σr)*r^2-(σθ+σr)*a^2)/(2*a^2))’

‘Po=-(((σθ-σr)*r^2-(σθ+σr)*b^2)/(2*b^2))’ ] }

Notice that the result includes a vector [ ] contained within a list { }. To remove

the list symbol, use µ. Finally, to decompose the vector, use function OBJ.

The result is:

These two examples constitute systems of linear equations that can be handled

equally well with function LINSOLVE (see Chapter 11). The following

example shows function SOLVE applied to a system of polynomial equations.

Example 3 - System of polynomial equations

The following screen shot shows the solution of the system X

using function SOLVE:

Solution to simultaneous equations with MSLV

Function MSLV is available as the last option in the ‚Ï menu:

The help-facility entry for function MSLV is shown next:
