Chapter 23, Problem 18P
Use the diff command in MATLAB and compute the finite-difference approximation to the first and second derivative at each x-value in the table below, excluding the two end points. Use finite-difference approximations that are second-order correct,
| x | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| y | 1.4 | 2.1 | 3.3 | 4.8 | 6.8 | 6.6 | 8.6 | 7.5 | 8.9 | 10.9 | 10 |

This can be modeled by the differential equation dT dt k(TA), where T is the temperature of the object after t units of time have passed, A is the ambient temperature of the object's surroundings, and k is a constant of proportionality.
