Frequently Asked Questions

JavaScript's `Math.sin()` and `Math.cos()` use **radians** by default. To use degrees, you must convert the input: `radians = degrees * (Math.PI / 180)`.

Yes. You can use a global variable to store the value and add buttons to add/recall that variable.

It uses `eval()` or `Function constructor`. While powerful, `eval()` can be unsafe if not restricted. It is best to parse the string manually or ensure only valid math characters are allowed.
