4.1 Imisebenzi Eyisisekelo
- Ukwengeza, Ukususa, Ukuphindaphinda, Ukuhlukanisa: Sebenzisa i- +, -, ×, ÷ okhiye.
- Kuyalingana: Cindezela = ukuthola umphumela.
- Sula Okufakiwe: Cindezela DEL to delete the last entered digit.
- All Clear: Cindezela AC to clear the entire calculation and display.
4.2 Imisebenzi Yesayensi
Access secondary functions printed above keys by pressing the SHIFT ukhiye kuqala, bese kuba ukhiye womsebenzi owufunayo.
- Trigonometry: Sebenzisa isono, cos, i-tan keys. Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) are accessed via SHIFT.
- Logarithms: Sebenzisa log (isisekelo 10) kanye ln (natural logarithm) keys.
- Amandla Nezimpande: Sebenzisa x², √, x³, ³√, xʸ okhiye.
- Factorial: Sebenzisa i- x! umsebenzi.
4.3 Fraction Calculations
The SC-216 simplifies fraction input and display.
Isithombe: A enemininingwane view of the calculator's fraction key ('ab/c') and its application in displaying results in both fraction and decimal formats.
- Inputting Fractions: Sebenzisa i- ab/c key to enter mixed numbers or improper fractions. For example, to enter 1 2/3, press 1 ab/c 2 ab/c 3.
- Converting Fractions/Decimals: Cindezela SHIFT bese ab/c (d/c) to toggle between fraction and decimal display.
4.4 Modes and Settings
Cindezela inkinobho MODE/CLR button to access different calculation modes.
- COMP (Compute): Standard arithmetic and scientific calculations.
- STAT (Statistics): For statistical calculations (1-variable or 2-variable).
- Ama-engeli: Toggle between Degrees (DEG), Radians (RAD), and Grads (GRA) using SHIFT + MODE/CLR.
- Incazelo yobunjiniyela: Sebenzisa i- ENG key to display results in engineering notation.
4.5 Replay Function
I DLALA futhi inkinobho ikuvumela ukuthi uphindeview and edit previous calculations.
- After a calculation, press the DLALA futhi button to scroll through previous entries and results.
- Use the arrow keys to navigate and edit expressions.
