Buddy the Elf asks Frosty for math help.
|
|
|
|
 | |  |
| Hey Frosty, do you know how to find a limit? I need to find the instantaneous speed of Santa's sleigh when it delivers presents on Christmas. | |
 | |  |
|
 |
| | |
| Why yes I do, Buddy. You must use a certain method to find a limit. The first step is direct substitution. | |
| | |
|
|
|
|
Frosty, who is very smart, helps Buddy the Elf with his homework.
|
|
|
|
| | |
| If that doesn't work, then you use the second step: simplify, and then substitute. | |
| | |
|
 |
| | |
| Ohhhhh......That's kind of hard to do in my head when I'm riding in a sleigh going 100 m.p.h! | |
| | |

When Santa asks Buddy for an answer, Buddy can't answer because he left his calculator at home.
|
|
|
|
| | |
| What is the instantaneous speed of my sleigh, Buddy? | |
| | |
|
 |
| | |
| Well...I don't know. Frosty told me to use the third step in finding a limit, but I can't approximate it because I forgot my calculator at the North Pole. | |
