3. Instrucciones de funcionamiento

This section provides a guide to the various functions and operations of your Casio fx-300MS Plus 2nd Edition Scientific Calculator.

3.1 Cálculos básicos

Introduzca números utilizando el teclado numérico y realice operaciones utilizando las teclas [+], [-], [×], y [÷] botones. prensa [=] para mostrar el resultado.

3.2 Funciones científicas

The calculator offers a wide array of scientific functions. Many functions are accessed by pressing the [CAMBIO] key followed by the desired function key (indicated in yellow above the keys).

• Funciones trigonométricas: Usar [pecado], [cos], [broncearse] para seno, coseno y tangente. Funciones inversas (pecado⁻¹, porque⁻¹, bronceado⁻¹) se accede a través de [CAMBIO].
• Logaritmos: Usar [registro] for base-10 logarithm and [en] for natural logarithm.
• Poderes y raíces: Usar [x²] para cuadrado, [√] para la raíz cuadrada, [x³] for cube, and [³√] for cube root. General powers ([^]) and roots ([SHIFT] [^]) are also available.
• Factoriales: Usar [¡incógnita!] (acceso a través de [CAMBIO]) for factorial calculations.

3.3 Cálculos de fracciones

The dedicated fraction key [abecedario] allows for easy entry and calculation of fractions and mixed numbers. Use [SHIFT] [a b/c] to convert between improper fractions, mixed numbers, and decimal equivalents.

3.4 Cálculos estadísticos

To enter Statistics Mode, press [MODO] and select the appropriate statistical option (e.g., SD for standard deviation, REG for regression). Follow the on-screen prompts to input data and perform calculations.

3.5 Variable Memory

The calculator can store up to 9 variables (A-F, X, Y, M). To store a value, enter the number, press [STO], and then press the alpha key corresponding to the desired variable (e.g., [ALPHA] [A]). To recall a value, press [RCL] and the variable key.

3.6 Modos y configuraciones

Presione el [MODO] button to cycle through different calculation modes (e.g., COMP for basic arithmetic, STAT for statistics). The [CONFIGURACIÓN] button (accessed via [SHIFT] [MODE]) allows you to configure display settings, angle units (degrees, radians, grads), and number formats.

3.7 Apagar

Para apagar la calculadora, presione [CAMBIO] seguido por [C.A] (APAGADO).

4.3 Reemplazo de batería

If the display becomes dim or calculations are slow, even in good lighting, it may be time to replace the LR44 backup battery. Refer to section 2.1 for battery installation instructions.

5. Solución de problemas

• La pantalla está en blanco: Ensure the calculator is in sufficient light for the solar panel. If it remains blank, replace the LR44 backup battery.
• Resultados incorrectos: Check the current mode (e.g., degrees vs. radians for trigonometric functions). Press [SHIFT] [MODE] to access setup and adjust settings. Ensure correct input of numbers and operations.
• La calculadora se congela: Presione el [C.A] button to clear the current calculation. If the issue persists, try removing and reinserting the battery to perform a hard reset.
• Los botones no responden: Ensure no debris is lodged under the keys. Clean the calculator as described in section 4.1.
