How to Use the Scientific Calculator
Step 1 – Select Angle Mode
Before solving trigonometric expressions, choose the appropriate angle unit.
Choose DEG if your angles are measured in degrees.
Example:
sin(30°)
Choose RAD if your values are measured in radians.
Example:
sin(π/6)
Step 2 – Enter Mathematical Expressions
Type expressions using either the calculator buttons or your physical keyboard.
Parentheses can be used to control the order of operations.
Example:
(25 + 15) × 4
Step 3 – Using the Nth Root Function
Suppose you want to calculate the fourth root of 81.
The mathematical expression is:
⁴√81
Steps:
- Enter 81
- Click the ⁿ√x button.
- Enter 4
- Press =
Result: 3
Step 4 – Using Memory Functions
- Enter a number.
- Press MS to save it.
- Continue your calculations.
- Press MR whenever you want to reuse the stored value.
- Press MC to clear the memory.
