How to Use the Scientific Calculator
- Enter numbers: Click the number buttons or type on your keyboard to enter values into the display.
- Select an operation: Choose basic operations (+, -, ×, ÷) or scientific functions (sin, cos, tan, log, ln, √, x², xʸ).
- Set deg/rad mode: For trigonometric functions, toggle between DEG (degrees) and RAD (radians) mode as needed.
- Use memory functions: Store values with M+/M-, recall with MR, or clear memory with MC for complex multi-step calculations.
- View result and history: Press = to see the result. Review previous calculations in the history panel.
