Frequently Asked Questions

1. What's the difference between DEG, RAD, and GRAD modes?

DEG uses degrees (0-360), RAD uses radians (0-2π), and GRAD uses gradians (0-400). Choose based on your problem requirements or preferences.

2. How do I calculate complex expressions?

Use parentheses to group operations. For example: sin(45) * cos(30) + log(100). The calculator follows standard mathematical order of operations.

3. What's the precision of calculations?

The calculator provides up to 15 significant digits of precision, suitable for most scientific and engineering calculations.

4. How do I calculate logarithms with different bases?

Use the change of base formula: log_b(x) = ln(x) / ln(b) or log(x) / log(b). For example, log base 2 of 8: ln(8) / ln(2).

5. Can I calculate large factorials?

Yes, but factorials grow very quickly. 170! is near the limit of standard precision. For larger values, consider logarithms or approximations.

6. How do I handle domain errors?

Functions like sqrt(-1), ln(-1), or 1/0 will show "Error". Check your input values and function domains before calculating.

7. What's the difference between ln and log?

ln is the natural logarithm (base e ≈ 2.718), while log is the common logarithm (base 10). Both are widely used in different contexts.

8. How do I calculate powers and roots?

Use x^y for powers (e.g., 2^3 = 8) and sqrt() for square roots. For nth roots, use x^(1/n), like cube root: x^(1/3).

9. Can I use keyboard input?

Yes! You can type numbers and basic operators. Use Enter for equals, Escape for clear, and Backspace to delete the last character.

10. Is this suitable for engineering calculations?

Absolutely! This calculator includes all standard scientific functions needed for engineering, physics, and advanced mathematics coursework.
