How the scientific calculator works

Calculate expressions safely, view step-by-step evaluations, and plot up to three functions on an interactive Cartesian graph. Includes calculation history and PDF export for student worksheets.

Method and assumptions

Figur evaluates arbitrary expressions and graphs up to three functions in a bounded domain. It supports power, square root, sine, cosine, tangent, logarithms, and factorial on finite numbers. Trigonometric inputs can use degrees or radians.

  • √x is limited to x ≥ 0 and logarithms to x > 0.
  • Tangent is rejected at odd multiples of 90° (degree mode).
  • Factorial is limited to whole numbers 0 through 170 to retain finite numeric results.

Worked example
