2. Упутство за употребу

2.1 Основне аритметичке операције

Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). Притисните = за приказ резултата.

  • Додатак: 5 + 3 = (Резултат: 8)
  • одузимање: 10 - 4 = (Резултат: 6)
  • множење: 7 × 2 = (Резултат: 14)
  • дивизија: 15 ÷ 3 = (Резултат: 5)

2.2 Научне функције

The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2nd F key followed by the desired function key.

  • Тригонометријске функције: Користите грех, цос, тан keys. For inverse functions, press 2nd F then the respective key (e.g., 2nd F грех for sin-1).
  • Logarithms: Користите лог (base 10) and ln (natural logarithm) keys.
  • Моћи и корени: Користите за квадрирање, for square root. For other powers, use yx.
  • разломци: Користите аб/ц key to enter and calculate fractions.

2.3 Функције меморије

The calculator includes independent memory (M) and variable memories (A-F, X, Y).

  • Store to Memory: Enter a value, then press СТО followed by the desired memory key (e.g., СТО M+ to store to M).
  • Recall from Memory: Притисните РЦЛ followed by the desired memory key.
  • Обриши меморију: Притисните M-CLR to clear all memories.

2.4 Избор режима

Притисните тастер МОДЕ key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).
