How to read the result
- Always confirm whether the calculator is in degree or radian mode before evaluating trig functions.
- Scientific functions are sensitive to domains, so negative roots or invalid factorials can change the result completely.
Common input mistakes
- Leaving the angle unit in radians when you expect degree-based trig results.
- Applying factorials or roots to values outside the valid domain.
