Common Calculations Examples
Example 1: Trigonometric Calculation
Calculate sin(30°) × cos(60°):
- Set angle mode to Degrees
- Enter: sin(30) × cos(60)
- Press equals: Result = 0.25
- Calculation: sin(30°) = 0.5, cos(60°) = 0.5, 0.5 × 0.5 = 0.25
Example 2: Logarithmic Calculation
Calculate log₁₀(100) + ln(e²):
- Enter: log(100) + ln(e^2)
- Press equals: Result = 4
- Calculation: log₁₀(100) = 2, ln(e²) = 2, 2 + 2 = 4
Example 3: Complex Expression
Calculate √(25) + (3² × 2) / 4:
- Enter: √(25) + (3^2 × 2) ÷ 4
- Use parentheses for proper order
- Press equals: Result = 11.5
- Calculation: √25 = 5, 3² = 9, 9×2 = 18, 18÷4 = 4.5, 5 + 4.5 = 9.5

Frequently Asked Questions (FAQs)
Q: How do I switch between degrees and radians?
A: Use the Angle Mode setting in the calculator settings panel. You can choose between Degrees (DEG), Radians (RAD), or Gradians (GRAD). Most scientific calculations use radians.
Q: What's the difference between log and ln?
A: log (or log₁₀) is base-10 logarithm, commonly used in engineering and science. ln (natural log) is base-e logarithm (e ≈ 2.71828), used in calculus and advanced mathematics.
Q: How do I calculate exponents like 2³?
A: Enter 2, press the x^y button, then enter 3, and press equals. Alternatively, use 2^3 syntax if available. For square, use x² button.
Q: Can I use parentheses for complex expressions?
A: Yes! Our calculator supports nested parentheses for complex expressions. Use ( and ) buttons to group operations and control calculation order (PEMDAS/BODMAS).
