What you can calculate
- Trigonometry: sin, cos, tan in degrees or radians.
- Logarithms: natural log (ln) and base-10 (log).
- Powers & roots: x^y, √x.
- Constants & notation: π, e, parentheses, scientific notation.
Examples
| Expression | Meaning |
|---|---|
| sin(30) | Sine of 30° (in degree mode) = 0.5 |
| log(1000) | Log base 10 → 3 |
| ln(e) | Natural log of e → 1 |
| √49 | Square root → 7 |
| (3+2)*(5/2) | Parentheses with mixed ops → 12.5 |
Tips for accuracy
- Make sure the angle mode (deg/rad) matches your input.
- Use parentheses to control precedence in long expressions.
- Round only at the end to avoid cumulative error.
