polynomial a x
n
[r , r , ..., r ]. For example, a vector whose roots are given by
1 2 n
[-1, 2, 2, 1, 0], will produce the following coefficients: [1, -4, 3, 4, -4, 0]. The

The SYS sub-menu

The SYS sub-menu contains a listing of functions used to solve linear systems.
The functions listed in this sub-menu are:
These functions are presented in detail in Chapter 11.

The TVM sub-menu

The TVM sub-menu contains functions for calculating Time Value of Money. This
is an alternative way to solve FINANCE problems (see Chapter 6). The
functions available are shown next:
The SOLVR sub-menu
The SOLVR sub-menu in the TVM sub-menu will launch the solver for solving
TVM problems. For example, pressing @) S OLVR, at this point, will trigger the
following screen:
As an exercise, try using the values n = 10, I%YR = 5.6, PV = 10000, and FV
= 0, and enter „[ PMT ] to find PMT = -1021.08.... Pressing L, produces
