- Example: Mba hikajiana 15 + 7: Tsindrio 1 5 + 7 =. Result: 22.
4.2 Asa ara-tsiansa
The calculator provides a wide array of scientific functions. Many functions require pressing the 2ndF key first to access secondary functions printed above the keys.
- Trigonometric Functions: Ampiasao Ny fahotana, Kosy, tan. For inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), press 2ndF then the respective trigonometric key.
- Asa logaritmika: Ampiasao HIDITRA (fototra 10) ary ln (logarithma voajanahary).
- Hery sy fakany: Ampiasao x² for squaring, √ for square root. For other powers (xʸ) or roots (ʸ√x), use the yˣ or ʸ√x asa.
- Ampahany: Ampiasao ny ab/c fanalahidy ho an'ny fampidirana sy fiovam-po amin'ny ampahany.
4.3 Asa Fahatsiarovana
The calculator has independent memory (M) and seven variable memories (A-F, X, Y).
- M+: Manampy ny sanda aseho amin'ny fahatsiarovana mahaleo tena.
- M-: Subtracts the displayed value from the independent memory.
- RCL: Recalls the value from memory.
- STO: Stores the displayed value into a variable memory. Press Što then the desired variable key (e.g., A).
4.4 Statistical Calculations
Tsindrio raha hiditra amin'ny fomba statistika MODE then select the appropriate statistical mode (e.g., STAT). Input data using the DATA CD key. The calculator can perform various statistical calculations, including mean, standard deviation, and regression analysis.
4.5 Angle Unit Modes
The calculator supports three angle unit modes: Degrees (DEG), Radians (RAD), and Gradians (GRAD). Press the DRG key repeatedly to cycle through these modes. The current mode is indicated on the display.
5. Fikojakojana
5.1 Fanadiovana
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator.
