A full-featured scientific calculator for trigonometry, logarithms, powers, roots, and more — right in your browser. Switch to the Basic tab for everyday arithmetic.
Type numbers and operators using the on-screen buttons, then press "=" to evaluate the expression. Trigonometric functions apply to the number currently shown on screen — enter a value first, then tap sin, cos, or tan. Toggle between Degrees and Radians using the switch above the button grid; this affects every trig function and its inverse.
M+ adds the displayed value to memory, M- subtracts it, and MR recalls the stored total back to the screen — useful for running totals across several calculations without writing numbers down.
| Button | Function |
|---|---|
| x², x³ | Square, cube |
| √x, ³√x | Square root, cube root |
| ln, log | Natural log (base e), common log (base 10) |
| 1/x | Reciprocal |
| n! | Factorial (whole numbers 0–170) |
| π, e | Mathematical constants pi and Euler's number |
Degrees split a full circle into 360 equal parts and are the more familiar unit for everyday geometry. Radians measure angles by arc length relative to the radius, with a full circle equal to 2π radians — this is the standard unit in most higher-level math and physics. Make sure the mode matches what your problem expects before using any trig function.
