Interactive Graph Plotter

This tool allows you to visualize mathematical functions by plotting them on an interactive graph. It's a powerful resource for students, educators, and professionals in fields like mathematics, physics, engineering, and economics.

Key Features:

Multiple Graphs: Plot several functions on the same graph to compare their behavior. Use the "Add Equation" button to create new function inputs.
Interactive Controls:
- Zoom: Use your mouse scroll wheel to zoom in and out of the graph to see fine details or a broader view.
- Pan: Click and drag the graph to move it around and explore different regions of the function.
- Trace: Hover your mouse over a line to see the precise (x, y) coordinates at that point.
Standard Functions: The plotter supports a wide range of mathematical functions, including:
- Basic operators: + - * / ^
- Trigonometric functions: sin(x), cos(x), tan(x)
- Exponential and logarithmic functions: exp(x), log(x)
- And many more from the standard math library.

Whether you're exploring the shape of a parabola, visualizing the period of a sine wave, or comparing different growth curves, this tool provides instant feedback and a deeper visual understanding of mathematical concepts.

Frequently Asked Questions

What functions can I plot?

You can plot most standard mathematical functions. The parser supports basic operators like `+, -, *, /, ^`, trigonometric functions (`sin`, `cos`, `tan`), inverse trigonometric functions (`asin`, `acos`, `atan`), logarithms (`log`, `log10`), exponentials (`exp`), and more. Always use `x` as your independent variable.

How do I write powers and square roots?

Use the `^` symbol for powers, for example, `x^2` for x-squared. For square roots, use the `sqrt()` function, like `sqrt(x)`. For other roots, you can use fractional exponents, for example, `x^(1/3)` for the cube root of x.

How do I zoom or pan the graph?

The graph is fully interactive. You can use your mouse scroll wheel to zoom in and out. To pan (move the graph around), simply click and drag the graph to your desired view. Double-clicking will reset the view to its default state.

Why does my function not appear or look strange?

This can happen for a few reasons. First, check your function for any syntax errors. Second, the function might be outside the current x-range of the graph. Third, for functions with vertical asymptotes (like `tan(x)`), the plotter attempts to handle them gracefully, but they can sometimes cause very large y-values that stretch the graph. Try zooming in on a smaller area.

How can I see the exact coordinates on a line?

Simply hover your mouse cursor over any of the plotted lines. A tooltip will appear that shows you the precise (x, y) coordinates for that specific point on the graph.
