How to Use the Scientific Calculator
- Basic Operations: Use number buttons (0-9) and basic operators (+, -, ×, ÷) for arithmetic
- Scientific Functions: Click function buttons (sin, cos, tan, log, ln, etc.) to apply to displayed number
- Angle Mode: Toggle between DEG (degrees) and RAD (radians) for trigonometric functions
- Constants: Insert mathematical constants π (pi) and e (Euler's number) directly
- Memory Functions: MS (store), MR (recall), MC (clear memory), M+ (add to memory)
- Power Operations: Use x² for square, x³ for cube, or x^y for any power
- Clear Functions: C clears current entry, AC clears everything including memory

Frequently Asked Questions
What's the difference between degrees and radians?
Degrees divide a circle into 360 parts, while radians use the radius length as the unit. One full circle = 360° = 2π radians. Toggle the mode with the DEG/RAD button.
How do I use the memory functions?
MS stores the current display value in memory, MR recalls it, MC clears memory to zero, and M+ adds the current value to what's already stored in memory.
What's the difference between log and ln?
log() calculates the base-10 logarithm (common logarithm), while ln() calculates the natural logarithm (base e). ln is commonly used in calculus and natural sciences.
Can I calculate complex expressions?
This calculator processes operations sequentially. For complex expressions with multiple operations, consider breaking them into steps or using parentheses carefully.
What happens if I get an error?
Errors occur with invalid operations like division by zero, square root of negative numbers, or factorial of non-integers. Press C or AC to clear and start over.
How accurate are the calculations?
The calculator uses JavaScript's built-in math functions with double-precision floating-point arithmetic, providing about 15-16 decimal digits of precision for most operations.
