FAQ
- Degrees or radians?
- This calculator uses degrees for sin, cos and tan, which matches most school calculators in degree mode.
- What does ^ do?
- It is the power operator: 2^10 means 2 to the 10th power, which is 1024.
- Why does my expression show an error?
- Usually an unbalanced parenthesis or two operators in a row. Check the expression and try again.
