The document references a C program from figure 13.12 that uses a nested for loop to calculate a mathematical series. It prompts the reader to express the computed quantity using mathematical symbols. Additionally, it mentions a table containing the initial values of the summation produced by the program.

1. Figure 13.12 in the text contains a C program with a nested for loop. Mathematically state the
series that this program calculates (that is, write the equation for the quantity computed using
mathematical symbols). Hint: The first several values of the summation are given in table. Table
2: First several values given by the program of Patt and Patel figure 13.12.
