What math operations and functions are supported?

It supports basic arithmetic (+, -, *, /, ^), constants (pi, e), and 20+ functions including sin, cos, tan, log, ln, sqrt, abs, ceil, floor, round, and advanced ones like log2, cbrt, trunc, sign, max, and min.

How do I use variables like x, y, or n in my formulas?

You can assign values to variables (x, y, z, a, b, n) in the Variables section. The calculator will automatically substitute these values into your expression for evaluation.

How do I switch between degrees and radians for trigonometry?

Simply select "Degrees (DEG)" or "Radians (RAD)" from the Angle Mode dropdown. This affects all trigonometric functions like sin, cos, and tan.

Does the calculator save my previous results?

Yes. Pressing the Enter key will save your current expression and its result to the History list (up to 10 entries) for quick reference.
