Frequently Asked Questions
Our graph plotter supports a wide range of mathematical functions including:
- Basic operations: +, -, *, /, ^ (exponentiation)
- Trigonometric: sin, cos, tan, asin, acos, atan
- Exponential and logarithms: exp, log (natural log), log10
- Constants: pi, e
- Absolute value: abs()
- Square root: sqrt()
Example: 2*sin(3*x) + cos(pi*x)
There are no hard limits on function complexity, but extremely complex functions may take longer to render or might not display correctly if they contain discontinuities or undefined regions. The tool is optimized for most common mathematical functions encountered in algebra, trigonometry, calculus, and engineering applications.
Currently, you can take a screenshot of your graph using your device's screen capture functionality. We're working on adding direct export options for images and PDFs in future updates. You can share your function expressions by copying the text from the input field.
