Example: To calculate sin(30):

1. Ensure the calculator is in DEG mode (see Display Modes).
2. Premeu 2n F, doncs pecat (which is the primary function of the key).
3. Entra 3, 0, després premeu =. La pantalla mostrarà 0.5.

EscriuView Mostra

L'EscripturaView feature allows you to input and display equations in a natural, textbook-like format.

• Enter equations as they appear in your textbook. The calculator will display fractions, roots, and other expressions clearly.
• Use the arrow keys (left, right, up, down) to navigate within an equation for editing.

Display Modes (DEG, RAD, GRAD)

The calculator supports three angle modes: Degrees (DEG), Radians (RAD), and Gradians (GRAD).

• To change the mode, press the MODE key repeatedly until the desired mode (DEG, RAD, o GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

Funcions de memòria

The calculator includes memory functions to store and recall values.

• M+ (Memory Plus): Adds the displayed value to the independent memory.
• M- (Memory Minus): Subtracts the displayed value from the independent memory.
• RCL (Recall Memory): Recalls the value stored in the independent memory.
• STO (Store Memory): Stores the displayed value into a specific variable memory (A, B, C, D, E, F, X, Y, M).

Fractions and Decimals

• Per introduir una fracció, feu servir la ab/c clau.
• To convert a fraction to a decimal or vice versa, press the 2n F tecla seguida de la tecla ab/c clau.

Statistical Functions

The calculator includes various statistical functions.

• Per entrar ESTADÍSTICA mode, premeu MODE clau fins a ESTADÍSTICA està seleccionat.
• Input data points and use the statistical function keys (e.g., mean, standard deviation) to perform calculations.
• Refer to the detailed function guide for specific statistical operations.

Manteniment

Proper maintenance ensures the longevity and optimal performance of your calculator.

Neteja

• Wipe the calculator's exterior with a soft, dry cloth.
