Graphing Calculator - Adlam Numerals
Plot and visualize mathematical functions with our interactive graphing calculator with Adlam numeral system support.
A free online graphing calculator for visualising mathematical functions. Plot up to 6 functions simultaneously with different colours to compare their shapes, find intersection points, and identify roots. Supports polynomials, trigonometric functions (sin, cos, tan), exponential and logarithmic functions, and any combination thereof. Zoom and pan controls let you explore the graph at any scale, from a broad overview to a close-up of a specific intersection point. Use standard mathematical notation: * for multiply, ^ for exponents, sqrt() for roots, sin() for trig functions.
About This Numeral System
Adlam numerals (U0001e950 through U0001e959) are the digits of the Adlam script, created in 1989 by two Guinean brothers, Ibrahima and Abdoulaye Barry, as a writing system for Fulani (Fula) — a Niger-Congo language spoken by roughly 25 million people across West Africa, including Guinea, Nigeria, Senegal, Mali, and Cameroon. The name “Adlam” is an acronym from the first four letters of the script, standing for “Alkule Dandayɗe Leñol Mulugol” — “the alphabet that prevents peoples from vanishing.” Adlam is written right-to-left and was added to Unicode in 2016. This calculator displays results in Adlam numerals for users who read and write in Fulani using the Adlam script.
How This Calculator Works
Function Plotting: y = f(x), evaluated at sampled x values
The graphing calculator samples the input function at regular intervals across the visible x-range, computes y = f(x) at each point, and plots the resulting coordinate pairs. Intersection points are found by detecting sign changes in f(x) − g(x) between adjacent samples and refining with bisection.
Worked Examples
Input: Plot y = x² and y = 2x on the same graph
Result: Intersection points: (0, 0) and (2, 4). The parabola opens upward; the line crosses it at the origin and at x = 2.
Key Features
- Up to 6 simultaneous functions
- Zoom and pan controls
- Intersection detection
- Export graph as image
Frequently Asked Questions
What functions can I plot?
You can plot any standard mathematical function including polynomials, trigonometric functions (sin, cos, tan), exponential and logarithmic functions, and combinations thereof.
Can I plot multiple functions at the same time?
Yes. You can plot up to 6 functions simultaneously with different colours to compare their shapes and intersections.
How do I find intersection points or roots?
Plot the functions you want to analyze. Intersection points appear where graphs cross, and roots (x-intercepts) appear where the function crosses the x-axis. Use the zoom and pan features to get precise visual readings of these points.
What is the syntax for entering functions?
Use standard mathematical notation: * for multiplication, / for division, ^ for exponents, sqrt() for square roots, sin(), cos(), tan() for trig functions, log() for base-10 logarithm, and ln() for natural logarithm. Use parentheses to group expressions, e.g., "(x+1)/(x-1)".
What angle modes are supported for trigonometric functions?
The calculator supports three angle modes: Degrees (DEG), Radians (RAD), and Gradians (GRAD). Select your preferred mode from the settings before plotting. For example, sin(90) in degree mode equals 1, while sin(π/2) in radian mode also equals 1.
Can I graph piecewise functions or inequalities?
The calculator currently focuses on continuous functions. For piecewise functions, you can plot each piece separately by adding multiple function expressions with appropriate domain restrictions using mathematical notation.
How is Adlam different from other scripts created in modern times?
Adlam is one of the few scripts intentionally created in the 20th century that has gained real adoption. Unlike Ol Chiki (created 1925 for Santali in India), Adlam was created in 1989 for Fulani in West Africa. Both scripts were designed to serve languages that lacked a dedicated writing system, but Adlam is written right-to-left (like Arabic) while Ol Chiki is written left-to-right. Adlam was added to Unicode in 2016, making it one of the newest scripts in the Unicode standard.
