Graphing Calculator

Graphing Calculator

Plot up to three functions, inspect their domain and estimate visible roots without sending formulas to a server.

The parser supports arithmetic, powers, parentheses, pi, e, sin, cos, tan, inverse trigonometry, square root, absolute value, logarithms, exponential, rounding, minimum and maximum. It never executes JavaScript.

Function samplingFor each x in the selected domain, evaluate y = f(x) with 81–321 evenly spaced samples.

Urugero rufatika

Graph sin(x) and 0.1*x^2-2 from −10 to 10 to compare their shapes and approximate visible intercepts.

Ibyafashwe nk'ukuri mu ibara

  • The x-domain is sampled at evenly spaced points rather than drawn from a symbolic curve.
  • Trigonometric functions use radians.
  • Visible roots are estimated from sampled zeros and sign changes.

Uko wasobanura igisubizo

  • Each chart represents one semicolon-separated function.
  • The displayed minimum and maximum describe sampled finite values only.
  • A missing intercept does not prove that the mathematical function has no root.

Amakosa akunze kubaho ugomba kwirinda

  • Writing 2x instead of the supported explicit multiplication 2*x.
  • Using degrees directly in sin, cos or tan without converting to radians.
  • Graphing across a discontinuity and interpreting the connecting samples as a real curve.
