To solve for P
and P
, use the command SOLVE from the S.SLV menu
i
o
(„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))' ] }
, i.e.,
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.
