4.1 Күйгүзүү/өчүрүү

• Калькуляторду иштетүү үчүн ON, басыңыз ON/C баскычы.
• Калькуляторду иштетүү үчүн ӨЧҮРҮҮ, басыңыз 2nd баскычынан кийин ӨЧҮРҮҮ баскычы.

5. Операция

This section outlines the general usage of the TI-30Xa calculator's primary functions. For detailed step-by-step instructions and advanced operations, please refer to the official User Manual PDF linked in the Support section.

5.1 Basic Arithmetic

Сандык баскычтоптун жардамы менен сандарды киргизиңиз жана операцияны колдонуп аткарыңыз +, -, ×, жана ÷ баскычтар. Басыңыз = натыйжаны алуу үчүн.

5.2 Илимий функциялар

Many scientific functions are accessed directly or by pressing the 2nd key first to access the secondary function printed above the button.

• Тригонометриялык: Колдонуу КҮНӨӨ, COS, ТАН. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), press 2nd then the respective trig button.
• Логарифмдер: Колдонуу LOG (base 10) or LN (натурал логарифм).
• Powers & Roots: Колдонуу x² квадраттоо үчүн, √x for square root. For other powers (yˣ) or roots (³√x), use the 2nd ачкыч.

5.3 Fraction Calculations

To enter fractions, use the a^b/_c баскычы. Мисалы үчүнample, to enter 1/2, press 1 a^b/_c 2.

5.4 Конверсиялар

The calculator supports various conversions. For example, to convert a fraction to a decimal, enter the fraction and press F↔D. Other conversions like degrees/radians/grads are typically accessed via the DRG баскычы.

5.5 Статистика

The TI-30Xa can perform one-variable statistics. Consult the full user manual for detailed steps on entering data and calculating mean and standard deviation.

6. Техникалык тейлөө

To ensure the longevity and optimal performance of your TI-30Xa calculator, follow these maintenance guidelines:

• Тазалоо: Wipe the calculator with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing же экран.
• Сактагыч: When not in use, store the calculator in its protective slide case to prevent scratches and damage to the keys or screen.
• Батарея: The calculator uses a Lithium Metal battery. While designed for long life, if the display becomes dim or unresponsive, the battery may need replacement. Refer to the full user manual for battery replacement instructions.
• Экстремалдуу шарттарды болтурбоо: Do not expose the calculator to extreme temperatures, humidity, or direct sunlight for prolonged periods.

7. Кыйынчылыктарды

If you encounter issues with your TI-30Xa calculator, try the following common troubleshooting steps:

• Калькулятор күйбөйт:
  • Ensure the battery is properly seated.
  • Эгер батарейка эски болсо, аны алмаштыруу керек болушу мүмкүн.
• Дисплей күңүрт же бош:
  • Бул көбүнчө батареянын заряды аз экенин билдирет. Батареяны алмаштырыңыз.
  • Ensure the calculator is not exposed to very cold temperatures, which can affect LCD performance.
• Туура эмес эсептөөлөр:
  • Double-check your input.
  • Ensure you are using the correct function keys and order of operations.
  • Clear the calculator's memory by pressing ON/C or performing a reset if necessary (refer to the full manual for reset procedures).

For more complex issues, refer to the detailed troubleshooting section in the official User Manual PDF.
