Using the app

Use the exam-style formula sheets

Open a one-page formula sheet for algebra, geometry, precalculus, calculus, statistics or physics, and print it.

Open in Trident

1. Open the reference library and choose the Labs chip, then open Formula sheets (it is free).
2. Choose a sheet: Algebra 1, Geometry, Algebra 2 & Precalc, Calculus, Statistics or Physics. The app remembers which sheet you used last.
3. Read down the sections (for example Quadratics & factoring, Derivatives, or Motion). Each row shows a name and the formula.
4. Tap Open on a row to go to the related formula card, shape, toolkit or lab and try it with live numbers. Use "Back to library" to return.
5. Tap Print to print the sheet or save it as a PDF.
