About This Tool

What is Calcolatrice?

A tool for evaluating math expressions directly. Supports arithmetic operations plus trigonometric functions, logarithms, exponents, and mathematical constants (pi, e). Maintains a calculation history.

How to Use

  1. Enter a math expression (e.g., 2+3*4, sin(pi/2)).
  2. Press Enter to see the result.
  3. View previous calculations in the history.
  4. Click 'Clear History' to reset.

Key Features

  • Arithmetic operations with parentheses
  • Trigonometric functions (sin, cos, tan), logarithms (log, ln)
  • Built-in math constants (pi, e)
  • Calculation history retention

Tips

  • Use * for multiplication, / for division, and ** for exponentiation.
  • pi equals 3.14159..., e equals 2.71828... as mathematical constants.
  • Use parentheses to explicitly set operation order in complex expressions.
