Function samplingFor each x in the selected domain, evaluate y = f(x) with 81–321 evenly spaced samples.
Një shembull praktik
Graph sin(x) and 0.1*x^2-2 from −10 to 10 to compare their shapes and approximate visible intercepts.

Supozimet e llogaritjes
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.
Si të interpretohet rezultati
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.
Gabime të zakonshme për t'u shmangur
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.
