Chapter 5.5, Problem 1QCE

In each part, use the partition of $\left[2,7\right]$ in the accompanying figure.

(a) What is $n$ , the number of subintervals in this partition?

(b) $x_0=\text{\_\_\_\_\_\_\_; }{x}_1=\text{\_\_\_\_\_\_\_; }{x}_2=\text{\_\_\_\_\_\_\_; }{x}_3=\text{\_\_\_\_\_\_\_; }{x}_4=\text{\_\_\_\_\_\_\_}$

(c) $\Delta x_1=\text{\_\_\_\_\_\_\_; }\Delta x_2=\text{\_\_\_\_\_\_\_; }\Delta x_3=\text{\_\_\_\_\_\_\_; }\Delta x_4=\text{\_\_\_\_\_\_\_;}$

(d) The mesh of this partition is $\text{\_\_\_\_\_\_\_}$ .
