|---|---|---|
| sin, cos, tan | Trigonometric functions | sin(30) = 0.5 in DEG |
| sin⁻¹, cos⁻¹, tan⁻¹ | Inverse functions (angle from a ratio) | sin⁻¹(0.5) = 30 in DEG |
| xʸ, x² | Powers | 2^10 = 1,024 |
| √ | Square root | √(144) = 12 |
| log, ln | Base-10 and natural logarithms | log(1000) = 3 |
| n! | Factorial | 5! = 120 |
