How to Use the Scientific Calculator
Basic Operations
- Enter numbers using the numeric keypad
- Use +, -, ×, and ÷ for basic arithmetic
- Press = or Enter to calculate the result
- Use C to clear and ⌫ to delete the last entry
Scientific Functions
- Trigonometric: Use sin, cos, and tan with angles in degrees (e.g., sin(90) = 1)
- Logarithmic:
- 'log' calculates base-10 logarithm
- 'ln' calculates natural logarithm
- Constants:
- 'π' represents Pi (3.14159...)
- 'e' represents Euler's number (2.71828...)
Advanced Operations
- Power: Use x^y for exponents (e.g., 2^3 = 8)
- Square Root: Use √ for square root (e.g., √(16) = 4)
- Factorial: Use ! for factorial (e.g., 5! = 120)
- Percentage: Use % for percentage calculations
Keyboard Shortcuts
- Enter: Calculate result
- Backspace: Delete last character
- Escape: Clear display
- Numbers and operators (+, -, *, /) work directly from keyboard
Tips
- Always close parentheses when using functions (e.g., sin(45))
- For complex calculations, use parentheses to group operations
- If you see an error, press C or wait for automatic clear
