Tips for Using the Scientific Calculator
- Always check whether you need DEG (degrees) or RAD (radians) mode for trigonometric calculations.
- Use the INV button to access inverse functions like arcsin, arccos, and arctan.
- Use parentheses ( ) to group operations and ensure correct calculation order.
- The memory functions are useful for storing intermediate results in complex calculations.
- Click on any history item to reuse that result in your current calculation.
