ऑपरेटिंग सूचना

This section details the basic operation and function usage of your Sharp EL-W531TL scientific calculator.

मूलभूत अंकगणितीय ऑपरेशन्स

Perform standard addition, subtraction, multiplication, and division using the dedicated keys (+, -, ×, ÷).

• Enter numbers and operators sequentially. Press the = key to display the result.

Example: To calculate 15 + 7:

दाबा 1, 5, +, 7, =. डिस्प्ले दिसेल 22.

Function Access (2nd F Key)

Many keys have secondary functions printed above them. To access these functions, press the दुसरा एफ key first, then the desired function key. The "2nd F" indicator will appear on the display.

Example: To calculate sin(30):

1. Ensure the calculator is in डीईजी mode (see Display Modes).
2. दाबा दुसरा एफ, नंतर पाप (which is the primary function of the key).
3. प्रविष्ट करा 3, 0, नंतर दाबा =. डिस्प्ले दिसेल 0.5.

लिहाView डिस्प्ले

लिहाView 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 (डीईजी), Radians (आरएडी), and Gradians (ग्रॅड).

• To change the mode, press the मोड key repeatedly until the desired mode (डीईजी, आरएडी, किंवा ग्रॅड) is highlighted or selected.
• The current angle mode is indicated on the display.

मेमरी फंक्शन्स

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.
• आरसीएल (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 अ/क की
• To convert a fraction to a decimal or vice versa, press the दुसरा एफ की त्यानंतर अ/क की

सांख्यिकीय कार्ये

The calculator includes various statistical functions.

• प्रवेश करण्यासाठी STAT मोड, दाबा मोड की पर्यंत STAT निवडले आहे.
• 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.

देखभाल

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

साफसफाई

• कॅल्क्युलेटरचा बाहेरील भाग मऊ, कोरड्या कापडाने पुसून टाका.
