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.

¿Qué es esta calculadora científica?

Una calculadora científica online gratuita con las funciones de una calculadora de bolsillo clásica: trigonometría con selector DEG/RAD, logaritmos decimal y natural, potencias y raíces, factorial, las constantes π y e, paréntesis, porcentajes, memoria y una tecla ANS que recupera el resultado anterior.

Funciones

Trigonometría — sin, cos, tan y sus inversas. Revisa DEG/RAD: sin(90) = 1 en grados.
Potencias y raíces — x², ^ (2^10 = 1024), √ y ⁿ√ como root(n, x): root(3, 27) = 3.
Logaritmos — log (base 10) y ln (base e).
Factorial — 5! = 120, hasta 170!.

Teclado

Dígitos, + - * / ^ % !, Enter para igual, Escape para borrar, Backspace para retroceder.

Limitaciones

Unas 15 cifras significativas; los resultados muy grandes se muestran en notación científica.
Las operaciones indefinidas muestran un mensaje de error claro.
