Example: To calculate sin(30):

1. Ensure the calculator is in DEG mode (see Display Modes).
2. Stiskněte 2. F, pak hřích (which is the primary function of the key).
3. Vstupte 3, 0a poté stiskněte =. Na displeji se zobrazí 0.5.

NapsatView Zobrazit

The WriteView 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, RADnebo GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

Paměťové funkce

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

• To enter a fraction, use the ab/c klíč.
• To convert a fraction to a decimal or vice versa, press the 2. F klíč následovaný klávesou ab/c klíč.

Statistické funkce

The calculator includes various statistical functions.

• Chcete-li vstoupit STAT stiskněte tlačítko MODE klíč do STAT je vybráno.
• 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.

Údržba

Správná údržba zajistí dlouhou životnost a optimální výkon vaší kalkulačky.

Čištění

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