How do I use trigonometric functions?+
Click sin, cos, or tan, then enter the angle. Make sure DEG or RAD mode is set correctly.
What is the difference between log and ln?+
log is base‑10 logarithm; ln is natural logarithm (base e).
How do I use memory functions?+
Use MC to clear memory, M+ to add the displayed value, M− to subtract, and MR to recall the stored value.
Can I use the keyboard?+
Yes! Type numbers, operators (+, -, *, /), parentheses, Enter for equals, Backspace to delete, Escape to clear.
