A graphing calculator for formulas, functions, and quick checks
This calculator combines regular arithmetic, scientific functions, and graph plotting. It is useful for studying, checking formulas, quick calculations, and seeing how a function behaves without opening a desktop app.
What you can do
- Solve expressions with parentheses, fractions, percentages, powers, and roots
- Use sin, cos, tan, log, ln, sqrt, powers, and factorial
- Plot a function using a formula with the variable x
- Switch between calculator, graph, and split view modes
- Keep calculation history for quick review
Function graphing
- Quadratic, trigonometric, logarithmic, and mixed expressions
- Functions like x^2, sin(x), x^3 - 2*x + 1, and similar formulas
- Set a custom X-axis range for the part of the graph you need
- Automatic scaling on the Y-axis
- Preview the curve before using it in homework, reports, or deeper analysis
Modes:
- Calculator
- Graph
- Both
Example tasks
For calculations, try expressions such as sin(pi/2), sqrt(16), 2^3, log(100), fractions, parentheses, and powers.
For graphs, try x^2, sin(x), x^3 - 2*x + 1, and other formulas that use x.
