Plot up to three functions, inspect their domain and estimate visible roots without sending formulas to a server.
IFHEM IT-TWEĠIBA
Kif jiġi kkalkulat dan?
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.
Eżempju prattiku
Graph sin(x) and 0.1*x^2-2 from −10 to 10 to compare their shapes and approximate visible intercepts.
Suppożizzjonijiet, interpretazzjoni u żbalji komuni
Suppożizzjonijiet tal-kalkolu
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.
Kif tinterpreta r-riżultat
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.
Żbalji komuni li għandhom jiġu evitati
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.
