When you are in the |
|
Equation Writer and press |
|
, a menu of |
|
additional CAS functions |
|
available to you is |
|
displayed. Many of the |
|
functions in this menu |
|
match the functions available from the | |
the Equation Writer; but there are other functions that are | |
only available from this menu. This section describes CAS | |
functions that are available when you press | in the |
Equation Writer (grouped by main menu name). |
|
| All the functions on this menu are also available on the |
| menu in the Equation Writer. See “ALGB menu” |
| on page |
Complex menu |
|
i | Inserts i (= |
ABS | Determines the absolute value of the argument. |
| Example |
| Typing ABS(7 + 4i) yields 65 , as does ABS(7 – 4i). |
ARG | See “ARG” on page |
CONJ | See “CONJ” on page |
DROITE | DROITE returns the equation of the line through the |
| |
| Cartesian points, z1, z2. It takes two complex numbers, z1 |
| and z2, as arguments. |
| Example |
| Typing: |
| DROITE((1, 2), (0, 1)) |
| or: |
| DROITE(1 + 2·i, i) |
