5. ब्याट्री कम्पार्टमेन्ट कभर बदल्नुहोस् र यसलाई पेंचको साथ सुरक्षित गर्नुहोस्।

पावर अन/अफ

• To turn the calculator on, press the ON/C बटन।
• To turn the calculator off, press the दोस्रो एफ बटन पछि बन्द बटन।

सञ्चालन निर्देशनहरू

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

आधारभूत अंकगणितीय सञ्चालनहरू

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

• Enter numbers and operators sequentially. Press the = परिणाम प्रदर्शन गर्न कुञ्जी।

Example: To calculate 15 + 7:

थिच्नुहोस् 1, 5, +, 7, =। डिस्प्ले देखाउनेछ 22.

Function Access (2nd F Key)

Many keys have secondary functions printed above them. To access these functions, press the दोस्रो 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 DEG mode (see Display Modes).
2. थिच्नुहोस् दोस्रो एफ, त्यसपछि पाप (which is the primary function of the key).
3. प्रविष्ट गर्नुहोस् 3, 0, त्यसपछि थिच्नुहोस् =। डिस्प्ले देखाउनेछ 0.5.

लेख्नुहोस्View प्रदर्शन

लेख्नुहोस्View 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 मोड key repeatedly until the desired mode (DEG, RAD, वा GRAD) is highlighted or selected.
• The current angle mode is indicated on the display.

मेमोरी प्रकार्यहरू

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

• अंश प्रविष्ट गर्न, प्रयोग गर्नुहोस् ख/ग कुञ्जी।
• To convert a fraction to a decimal or vice versa, press the दोस्रो एफ कुञ्जी पछि ख/ग कुञ्जी।

तथ्याङ्कीय कार्यहरू

The calculator includes various statistical functions.

• प्रवेश गर्न STAT मोड, थिच्नुहोस् मोड कुञ्जी सम्म STAT चयन गरिएको छ।
• 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.

मर्मतसम्भार

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

सरसफाई

• क्याल्कुलेटरको बाहिरी भाग नरम, सुख्खा कपडाले पुछ्नुहोस्।
