 | Well, its useful for hard- to solve equations- such as distance based equations, and that really does prove useful. | |
|
| Really? | |
|
|
|
|
|
|
| Yes- for example, if you were asked for an expression for the total flying time for a distance of 1610 km from Miami to Wahsington, and then another 634 km to Tronoto, based on the speed, could you solve it? | |
|
| No.... | |
|
|
|
|
|
|
| Well, with this you can, and that makes it useful. | |
|
| So, like I said, is it useful? | |
