How to Use the Scientific Calculator

1

Use the number buttons (0-9) to input numbers and the decimal point (.) for decimal numbers.

2

Click on function buttons (sin, cos, tan, log, ln, etc.) to apply mathematical functions.

3

Use parentheses ( ) to group operations and control the order of calculations.

4

Toggle between DEG (degrees) and RAD (radians) mode for trigonometric functions.

5

Use memory functions (MR, MC, M+, M-) to store and recall values during calculations.
