Mathematics · LaTeX formulas, function graphs & PDF worksheets
In a real math lesson you need fractions, radicals, a coordinate system, and room for student corrections. In Lucyboard, the LaTeX formula editor, function grapher, scientific calculator, and PDF worksheets live together on one collaborative canvas.
Real lesson scenarios from tutoring sessions
Instead of sketching a sine wave freehand with a mouse, insert a coordinate grid with both functions plotted in radians. Place the Pythagorean identity and π/2 phase shift right beside it so the student sees the intersection at x = π/4 on the grid.
Formula editor with symbol palettes for fractions, roots, Greek letters, and mathematical operators.
No need to memorize commands like \frac or \sqrt. The “Mathematical formula” dialog provides one-click buttons for fractions, powers, roots, sums, integrals, and Greek letters, with a live rendered preview on the right.
Built-in scientific calculator — fast computation without switching tabs or grabbing a handheld calculator.
The built-in calculator handles trigonometric functions, logarithms, and powers. Clicking “+ Insert” drops the computed answer directly onto the board right where the student is working.
Structuring tutoring sessions
Drop in an exam paper or problem set PDF. Each document page becomes its own board page, surrounded by open canvas for working out equations, auxiliary sketches, and function plots.
The student joins via link without creating an account. Keep access on “Edit” while they solve the problem, or switch to “View” when you want to derive a formula without accidental moves.
The free Basic plan stores up to 10 permanent boards across 5 folders with PNG export. The Pro plan unlocks unlimited boards in up to 50 folders and multi-page PDF export.
No. The “Mathematical formula” window provides one-click symbol buttons for powers, subscripts, square roots, a/b fractions, sums, integrals, π, Δ, and inequalities, plus expandable palettes under “More”. A live preview updates as you type.
Open the calculator from the tools menu and switch to “Scientific” mode for sin, cos, tan, log, ln, square roots, powers xʸ, and constants π and e. Clicking “+ Insert” places the calculated result directly onto the board as text.
Yes. When you import a PDF exam paper in document mode, each page becomes a separate board page with open canvas margin around it for scratch calculations and function graphs.
Yes. The board runs in the browser across desktops, laptops, and tablets. A student can write freehand with a stylus while you insert LaTeX formulas or function plots from your keyboard.
You can keep the board in the student’s folder (up to 10 permanent boards across 5 folders on the free Basic plan; unlimited on Pro) or export it as a PNG image or multi-page PDF document (Pro).
Open a free board in your browser. No credit card, no app installs, and no accounts required for students.
