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.

O que é esta calculadora científica?

Uma calculadora científica online gratuita com as funções de uma calculadora de bolso clássica: trigonometria com seletor DEG/RAD, logaritmos decimal e natural, potências e raízes, fatorial, as constantes π e e, parênteses, porcentagens, memória e a tecla ANS que recupera o resultado anterior.

Funções

Trigonometria — sin, cos, tan e as inversas. Verifique DEG/RAD: sin(90) = 1 em graus.
Potências e raízes — x², ^ (2^10 = 1024), √ e ⁿ√ com root(n, x): root(3, 27) = 3.
Logaritmos — log (base 10) e ln (base e).
Fatorial — 5! = 120, até 170!.

Teclado
