Scientific Calculator
A full scientific calculator: trigonometry in degrees or radians, powers, roots, logs, factorials, memory and a history you can reuse.
DEG
Type with your keyboard too — Enter for =, Esc to clear.

How to use it
- Tap the keys or type with your keyboard. The answer shows as you type; press = (or Enter) to keep it in the history. Unclosed brackets are closed for you.
- 2nd switches keys to their second function: sin⁻¹, cos⁻¹, tan⁻¹, x³, ∛, nCr, sinh, log₂, mod and more.
- DEG / RAD sets the angle unit for sin, cos and tan. In degrees, common angles are exact: sin 180 = 0 and tan 90 is undefined.
- Multiplication can be left out:
2π,3(4+1)and2sin30all work. - % works like a desk calculator:
200 + 10%is 220, and200 × 15%is 30. - Ans is the last answer, and M+ / M− / MR / MC keep a running total in memory.
Functions you can type
sin cos tan asin acos atan sinh cosh tanh,ln log log2 logb(x, base),sqrt cbrt root(x, n) abs exp floor ceil round,nCr(n, r) nPr(n, r),x mod yandn!(non-whole numbers use the gamma function).
