Using Python 3.6 Coding
Exercise 7.18. Make a class for summation of series Our task in this exercise is to calculate a sum S(x)-M fk(z), where f(x) is a term in a sequence which is assumed to decrease in absolute value. In class Sum, for computing S(x), the constructor r quires the following three arguments: fk(x) as a function f(k, x). M as an int object M, and N as an int object N. A__call__ method com- putes and returns S(x). The next term in the series, fN+1(x), should be computed and stored as an attribute first_neglected_term. Here is an example where we compute S(2) = 0(-x)": def term(k, x): return (-x)**k S = Sum (term , M=0 , N-100) x = 0.5 print S(x) # Print the value of the first neglected term from last S(x) comp print S.first_neglected_term Calculate by hand what the output of this test becomes, and use it to verify your implementation of class Sum Apply class Sum to compute the Taylor polynomial approximation for sinx at x .30 and N-5. 10. 20. pare with the first neglected term fN+1(x). Present the result in nicely formatted tables. Repeat such calculations for the Taylor polynomial for e-r at x 1 . 3.5 and N = 5. 10. 20. Also demonstrate how class Sum can be used to calculate the sum (3.1) on page 98 (choose r- 2,5,10 and N - 5,10, 20). Formulas for the Taylor polynomials can be looked up in Exercise 5.27.
