How to Use

Basic Operations

  • • AC - Clear all
  • • +/- - Toggle positive/negative

Trigonometric Functions

  • • sin, cos, tan - Enter number then press function
  • • RAD/DEG - Toggle between radians and degrees
  • • Example: Enter 45, press "sin" for sin(45°)

Logarithms & Exponents

  • • log - Base-10 logarithm
  • • ln - Natural logarithm (base e)
  • • x², x³ - Square and cube
  • • Example: Enter 100, press "log" for log₁₀(100) = 2

Other Functions

  • • √ - Square root
  • • ! - Factorial (integers only)
  • • π, e - Mathematical constants
  • • ( ) - Parentheses for grouping

Examples

  • • sin(30°): 30 → sin
  • • log(100): 100 → log
  • • 5² + 3³: 5 → x² → + → 3 → x³ → =
  • • √(16): 16 → √

Quick Tips

  • • Use parentheses to group complex expressions
  • • Switch between RAD/DEG for trigonometric functions
  • • Factorial works only with positive integers
  • • Large/small numbers auto-format to scientific notation
  • • Press AC to reset calculator completely
  • • Use backspace (⌫) to correct individual entries
  • • Toggle +/- for negative numbers
