Summary including 8, 10, and 15 digits

Here are results obtained when the system we have been using in this section is solved without and with partial pivoting with digits set at various values.

Without Partial Pivoting

There is some improvement with partial pivoting although a couple of these are still not all that close to the answer of (1, 3, 2) which we obtained in the section, "Where did the plane go?".

Note that Maple's symbolic solve command, solve, will get (1., 3., 2.) as seen below.

> solve({6*x+6*y+3.00001*z=30.00002,10*x+8*y+4.00003*z=42.00006,6*x+4*y+2.00002*z=22.00004},{x,y,z});
