CHAPTER 3
• This function is explained using an example.
<Example>
The quadratic equation “ax
2
+ bx + c = 0” is solved using
parameters “a=2”, “b=-5” and “c=-3”.
1. Press Ï
C 2 .
(Select quadratic equation)
The screen shown on the right will appear asking for
input of each parameter. Since the cursor pointer is
positioned at “a”, enter starting with value a.
2. Complete parameter entry by pressing 2 ® — 5 ® — 3 ® .
3. Press Ï
to execute calculation as shown on the
right.
• To solve cubic equations, press Ï
C 3
then input each parameter following the example
mentioned above (for cubic equations, four parameters of a to d are entered).
•“ ” symbol will appear on the bottom left of the screen if the solution cannot be
shown on the screen at one time. Use ≥ to scroll the screen.
