Plot up to three functions, inspect their domain and estimate visible roots without sending formulas to a server.
FAHAMI JAWAPAN
Bagaimanakah ini dikira?
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.
Contoh praktikal
Graph sin(x) and 0.1*x^2-2 from −10 to 10 to compare their shapes and approximate visible intercepts.
Andaian, tafsiran dan kesilapan biasa
Andaian pengiraan
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.
Cara mentafsir hasil
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.
Kesilapan biasa yang perlu dielakkan
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.
