Frequently Asked Questions
How do I switch between degrees and radians?
Click the "Degrees" or "Radians" toggle at the top of the calculator. This affects all trigonometric functions (sin, cos, tan and their inverses).
Can I use keyboard input?
Yes. Type numbers and operators on your keyboard. Press Enter to evaluate, Escape to clear, and Backspace to delete the last character.
What is the memory function?
MC clears the memory, MR recalls the stored value, and M+ adds the current display value to the memory. This is useful for intermediate results in multi-step calculations.
