3. Fametrahana
3.1 Loharanon-kery
The Sharp EL-W531 calculator operates using both solar power and a single AAA battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.
3.2 Fametrahana/fanoloana bateria
- Ataovy azo antoka fa maty ny kajy.
- Tadiavo ao ambadiky ny kajy ny fonon'ny fitoeran'ny bateria.
- Using a small screwdriver, carefully remove the screw securing the cover.
- Esory ny fonony.
- Remove the old AAA battery (if applicable) and insert a new AAA battery, ensuring correct polarity (+/-).
- Soloy ny fonon'ny batterie ary arotsaho amin'ny visy izany.
3.3 Herin'ny voalohany
Tsindrio ny ON/C button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.
4. Torolàlana miasa
4.1 Kajy fototra
Raha hanao asa arithmetika fototra:
- Ampidiro ny laharana voalohany.
- Tsindrio ny fanalahidin'ny fandidiana (+, -, ×, ÷).
- Ampidiro ny laharana faharoa.
- mpanao gazety = hanehoana ny vokatra.
4.2 SoratyView miseho
Ny SoratyView ny fampisehoana dia ahafahanao mampiditra sy view mathematical expressions as they appear in textbooks. Fractions, roots, and other complex expressions are displayed in a natural format. Use the navigation keys (up, down, left, right arrows) to move the cursor within an expression for editing.
4.3 Fomba fiasa
The calculator offers various modes for different types of calculations. Press the MODE key to cycle through available modes such as:
- NORMAL: Ho an'ny kajy aritmetika sy asa ankapobeny.
- STAT: Ho an'ny kajy statistika.
- EQN: For solving equations.
Refer to the on-screen indicators (e.g., DEG, RAD, GRAD) for the current angle unit. Press DRG► (azo idirana amin'ny alalan'ny F faharoa) to change the angle unit.
4.4 Asa ara-tsiansa
The EL-W531 includes 335 functions. Many functions are accessed directly, while others require pressing the F faharoa key first. Common functions include:
- Trigonometric: sin, cos, tan, and their inverse functions (sin-1, cos-1, noho izany-1).
- Logarithmic/Exponential: log, ln, 10x, ex.
- Power/Root: x2, √, xy, y√x.
- Ampahany: a b/c key for mixed numbers and improper fractions.
- fahatsiarovana: STO (store), RCL (recall), M+ (memory plus).
Consult the key labels and the calculator's display for specific function usage.
5. Fikojakojana
5.1 Fanadiovana
Mba hanadiovana ny kajy dia fafao moramora amin'ny lamba malefaka sy maina. Aza mampiasa mpanadio mikikisana, solvents, na lamba lena, satria mety hanimba ny c ireo.asing na singa anatiny.
