Units
Units that check your work
Type 75 kg and 9.81 m/s² and the force comes out as 735.75 N. Ask for it in kN or lbf instead. Add 2 m to 30 cm and get 2.3 m. If you add volts to amps, the line turns red and tells you why.
More about worksheets and units →Solving
Solve what a calculator cannot
A diode and a resistor from 5 V: two equations, two unknowns, one of them exponential. Write the equations under Given, call Find, and MathSheet returns 0.555 V and 4.445 mA - with their units.
More about solving →Control loops
Bode plots with crossover and phase margin
The loop gain of a buck converter with a Type III compensator, plotted straight from the transfer function. The plot reads off the crossover frequency (33.65 kHz) and the phase margin (55.9°) for you. Change a part and watch them move.
More about graphs →3D plots
Surfaces, contours and vector fields
Type a function of two variables into a 3D plot and drag to turn it. The same worksheet can show contour maps, bar charts, curves in space and vector fields.
More about graphs →Excel
From worksheet to Excel workbook
Save a sheet as an Excel workbook: every value becomes a named cell, every result a live formula, every graph a real chart. This chart was drawn by LibreOffice Calc from the workbook MathSheet saved for the buck converter sheet; the crossover and phase margin are live cells beside it.

Calculations you can read, check and hand on
A calculator gives you a number but forgets how you got it. A spreadsheet hides the formula inside a cell. In MathSheet the formula is the page: you see the equation, the values and the answer together, with units, in the order you worked it out.
- Place equations, text and plots anywhere on the page
- Results update the moment an input changes
- Mistakes are marked in red with a plain-English explanation
- Works offline - your files stay on your computer
Made for engineering work
One tool, many disciplines
Electrical
Filters, impedances with complex numbers, component values with units, decibels.
Power electronics
Duty cycle, ripple, losses, and the converter loop gain with its phase margin.
Control systems
Transfer functions, Bode plots, Laplace transforms, and matrix equations such as the Riccati equation.
Mechanical
Forces, energy and heat flow in SI or US units, and best designs with Maximize and Minimize.
Applied math
Calculus, series, limits, matrices and symbolic answers as formulas.
Learning
Built-in lessons, a user manual and more than 80 example sheets that teach each feature step by step.
