What you can do
- Type up to eight equations as you would in a notebook: lines, parabolas, trigonometric functions, absolute value, roots, logarithms, circles and vertical lines.
- Mark intersections and zeros with their coordinates, and show the solution of an inequality such as f(x) > g(x) on the x-axis.
- Add a sign table under the graph and plot labelled points with dashed guide lines to the axes.
- Set the range and step of each axis, including steps in π, and style the grid, axes and legend, with a decimal point or comma.
- Download a print-quality PNG or an SVG, with a transparent background if you need one, or copy the image straight into a document.
