Which functions you can plot
Linear and quadratic
A line and a parabola with roots and vertex marked. The backbone of school function problems.
Exponential and logarithmic
Exponential growth and its inverse, with axes scaled to the range so the graph stays readable.
Trigonometric
Sine, cosine and tangent with the period visible on the axis, for identity and shift problems.
A graph on a board, not in isolation
Write the working beside it in mathematical notation, draw a figure or add a note for the student.
How to plot a graph
Open a board
Create a free account and start a new board. Math tools are in the left-hand panel.
Type the formula
Pick the graph tool and enter the formula. The graph is drawn immediately, with grid and axes.
Annotate and share
Add the working beside it, mark the key points, then send a link or export everything to PDF.
Frequently asked questions
Do I need to know LaTeX?
No. Enter the formula in ordinary notation and the tool typesets it. LaTeX is there when you want to write something more involved.
Can I plot several functions on one set of axes?
Yes. Add further graphs to the same board to compare shapes or show how a graph shifts.
Can the graph be exported?
Yes. Save the whole board with its graphs to a PDF file and send it straight from the app.
Does it work on a phone?
Yes. The board opens in a phone or tablet browser and the tool layout adapts to the screen size.
