• Due to the characteristics of Newton’s Law, the following scientifi c functions tend to make
it diffi cult to obtain solutions.
- Periodic functions (like
y
= sin(
x
))
- Functions that produce steep slopes when graphed (like
y
=
e
x
,
y
=
1
x
)
- Discontinuous functions (like
y
=
'
x
)

Variable solved for Solution
(Left Side) – (Right Side) result
• Solutions are always displayed in decimal format.
• When natural display is selected as the calculator’s display format, the two lines “X=” and
“L–R” are displayed in one line. If any of the data in a line does not fi t on the screen, use
e
and
d
to scroll.
• “(Left Side) – (Right Side) result” shows the result when the right side of the equation
is subtracted from the left side, after assigning the obtained value to the variable being
solved for. The closer this result is to zero, the higher the accuracy of the solution.

Convergence in Progress Screen
The convergence in progress screen like the one shown below will appear on the display
when SOLVE is unable to obtain a solution after a certain number of calculations. Pressing
E
while this screen is displayed will resume with the calculation.

TABLE Mode Overview
The TABLE Mode lets you create an
x
and
f
(
x
) number table by specifying a range of values
to be substituted for the function
f
(
x
) and for
x
.
