How do I switch between degrees and radians?

Press the DEG/RAD key at the top-left of the keypad. The current mode is shown on the display. In DEG mode, sin(90) = 1; in RAD mode, sin(π/2) = 1.

How do I calculate powers and roots?

Use x² for squares, ^ for any power (2^10 = 1024), √ for square roots, and ⁿ√ for other roots — it types root( and takes two inputs: root(3, 27) is the cube root of 27, which equals 3.

ANS inserts the result of your previous calculation, so you can chain steps: after 6 × 7 = 42, pressing ANS + 1 = gives 43.

How do I use the inverse trig functions?

sin⁻¹, cos⁻¹ and tan⁻¹ compute the angle whose sine, cosine or tangent you enter. The answer comes back in the current angle mode — sin⁻¹(1) is 90 in DEG mode and π/2 ≈ 1.5708 in RAD mode.

What is the difference between log and ln?

log is the base-10 logarithm (log(1000) = 3) and ln is the natural logarithm, base e ≈ 2.71828 (ln(e) = 1). Both are defined for positive numbers only.

Can I type calculations with my keyboard?

Yes — digits, the + - * / ^ % ( ) keys, Enter for equals, Escape to clear, and Backspace to delete all work exactly like the on-screen keys.

How large a factorial can it compute?

Up to 170! — beyond that the result exceeds what standard floating-point numbers can represent, and the calculator reports an error instead of showing an inaccurate value.

Che cos'è questa calcolatrice scientifica?

Una calcolatrice scientifica online gratuita con le funzioni di una classica calcolatrice tascabile: trigonometria con selettore DEG/RAD, logaritmi in base 10 e naturale, potenze e radici, fattoriale, le costanti π ed e, parentesi, percentuali, memoria e il tasto ANS che richiama il risultato precedente.

Funzioni

Trigonometria — sin, cos, tan e le inverse. Controlla DEG/RAD: sin(90) = 1 in gradi.
Potenze e radici — x², ^ (2^10 = 1024), √ e ⁿ√ con root(n, x): root(3, 27) = 3.
Logaritmi — log (base 10) e ln (base e).
Fattoriale — 5! = 120, fino a 170!.

Tastiera

Cifre, + - * / ^ % !, Invio per l'uguale, Esc per cancellare, Backspace per correggere.

Limiti

Circa 15 cifre significative; i risultati molto grandi appaiono in notazione scientifica.
Le operazioni indefinite mostrano un messaggio di errore chiaro.
