Instruccions de funcionament
This section outlines the basic and advanced functions of your Casio fx-260 Solar II calculator.
Operacions aritmètiques bàsiques
Enter numbers using the numeric keypad and perform operations using the +, -, ×, i ÷ claus. Premeu = per mostrar el resultat.
- Clarificar entrada (C): Clears the last entered number or operation.
- Tot esborrat (AC): Clears all calculations and memory, returning the calculator to its initial state.
Configuració del mode
Premeu el botó MODE button to cycle through different calculation modes and settings. Common modes include:
- COMP (Computation): Càlculs aritmètics i científics estàndard.
- SD (Standard Deviation): Per a càlculs estadístics.
- REG (Regression): For regression analysis.
Use the arrow keys or MODE button to select the desired mode, then press = or the corresponding number.
Càlculs de fraccions
El d/c or ab/c key is used for entering and calculating with fractions.
- Entering Simple Fractions: Enter the numerator, press d/ci, a continuació, introduïu el denominador.
- Entering Mixed Numbers: Enter the whole number, press ab/c, introdueix el numerador, prem d/ci, a continuació, introduïu el denominador.
- Converting Fractions to Decimals: Premeu MAJÚS aleshores d/c (or the appropriate conversion key) to toggle between fraction and decimal display.
Funcions trigonomètriques
The calculator supports standard trigonometric functions (sine, cosine, tangent) and their inverses.
- Angle Units: Ensure the correct angle unit (DEG for degrees, RAD for radians, GRA for gradians) is selected. Press MODE repeatedly until the desired unit appears, or use MAJÚS + DRG (if available) to cycle. The current unit is indicated on the display.
- Sine (sin), Cosine (cos), Tangent (tan): Enter the angle value, then press the corresponding function key.
- Inverse Trigonometric Functions (sin-1, cos-1, bronzejat-1): Premeu MAJÚS, després el pecat, cos, o bronzejat key. Enter the value, then press =.
Logarithms and Exponents
- Common Logarithm (log): Premeu registre, introduïu el número i, a continuació, premeu =.
- Logaritme natural (ln): Premeu ln, introduïu el número i, a continuació, premeu =.
- Powers (xy): Enter the base, press xy, introduïu l'exponent i premeu =.
- Arrel quadrada (√): Premeu √, introduïu el número i, a continuació, premeu =.
- Square (x2): Introduïu el número i, a continuació, premeu x2.
Funcions de memòria
La calculadora inclou funcions de memòria per emmagatzemar i recuperar valors.
- Store to Memory (M+): Afegeix el valor mostrat a la memòria independent.
- Recall Memory (MR): Recalls the value stored in the independent memory.
- Clear Memory (M-): Subtracts the displayed value from the independent memory. To clear the memory completely, press MAJÚS aleshores M+ (MCL).
