This section outlines the various functions and operations of the EL-531WHBK calculator.
Figure 2: Operating the Sharp EL-531WHBK Scientific Calculator.
4.1 Əsas arifmetik əməliyyatlar
Rəqəm klaviaturasından istifadə edərək rəqəmləri daxil edin. +, -, ×, və ÷ keys for addition, subtraction, multiplication, and division, respectively. Press = nəticəni göstərmək üçün.
- Example: To calculate 15 + 7: Press 1 5 + 7 =. Result: 22.
4.2 Elmi Funksiyalar
The calculator provides a wide array of scientific functions. Many functions require pressing the 2ndF key first to access secondary functions printed above the keys.
- Triqonometrik funksiyalar: istifadə edin günah, cos, tan. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), press 2ndF then the respective trigonometric key.
- Loqarifmik Funksiyalar: istifadə edin log (10-cu baza) və ln (natural loqarifm).
- Güclər və Köklər: istifadə edin x² kvadratlaşdırma üçün, √ for square root. For other powers (xʸ) or roots (ʸ√x), use the yˣ or ʸ√x funksiyaları.
- Fraksiyalar: istifadə edin ab/c key for fraction input and conversion.
4.3 Yaddaş Funksiyaları
The calculator has independent memory (M) and seven variable memories (A-F, X, Y).
- M+: Adds the displayed value to the independent memory.
- M-: Subtracts the displayed value from the independent memory.
- RCL: Recalls the value from memory.
- STO: Stores the displayed value into a variable memory. Press STO then the desired variable key (e.g., A).
4.4 Statistical Calculations
To enter statistical mode, press MODE then select the appropriate statistical mode (e.g., STAT). Input data using the DATA CD key. The calculator can perform various statistical calculations, including mean, standard deviation, and regression analysis.
4.5 Angle Unit Modes
The calculator supports three angle unit modes: Degrees (DEG), Radians (RAD), and Gradians (GRAD). Press the DRG key repeatedly to cycle through these modes. The current mode is indicated on the display.
5. Baxım
5.1 Təmizləmə
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator.
5.2 Saxlama
