 Description
 The definition of a polynomial in summation notation, handwritten by yours truly (at age 67). The 'x' is the argument of the function p(x), the 'a' is an array of n+1 parameters (called coefficients). For each 'i' (integers ranging from 0 to n, all inclusive), the corresponding coefficient a[i] is multiplied by the ith power of the variable x, and the results of these multiplications are all added up.
For the programmers among us, this would be written in the C programming language as:
for (i = 0, p = 0.0; i <= n, i++) p+= a[i]*pow(x,(double)i);  Tags
