| 2 | 2 | Symbolic Minimum and Maximum |
| 3 | 3 | |
| 4 | | This function was introduced due to the fact that max and min were not |
| 5 | | able to deal with variables as expected. This function strives to be a better evaluator of |
| 6 | | expressions by waiting to evaluate if there are variables. |
| | 4 | Sage provides a symbolic maximum and minimum due to the fact that the Python |
| | 5 | builtin max and min are not able to deal with variables as users might expect. |
| | 6 | These functions wait to evaluate if there are variables. |

| 10 | 10 | sage: max(x,x^2) |
| 11 | 11 | x |
| 12 | 12 | sage: max_symbolic(x,x^2) |
| 13 | 13 | max(x, x^2) |

| 16 | 21 | sage: min(3,5,x) |
