Description:
Specifies
LBL
M for
the
function.
Specifies D as the un
known. Prompts for V
as
it
shows
the
current
value of V (used in
the
last example).
Resulting distance in
meters.

Example:
Finding
the
Roots
of
an
Equation. Consider the single-
variable equation
x3 - 5x2 - lOx =
-20.
Rearranging the equation so one side is zero yields
x3 - 5x2 -
10*
+ 20 = 0.
Horner's method (see chapter 5) simplifies this equation to use less
memory:
x(x(x - 5) - 10) + 20 = 0.
