Problem 2 - 40 points
The value of sin(x) can be approximated using a Maclaurin series
x³ x5 x7
3! 5! 7!
sin(x) = x -
which can be expressed more compactly as
+
∞
x(k-1)*2+1
Σ(−1)k~¹ (k − 1) + 2 + 1)!
− *
(recall that the symbol ! stands for factorial, i.e., 3!=3×2×1).
a) Write a for loop to determine sin(2) using 5 terms (k=5).
b) Use a midpoint break loop to determine how many terms must be included
in the summation, in order to find the correct value of sin(2) within an error
of 0.001. Limit the number of iterations to a maximum of 10.
c) Create a function called my_sin to approximate the value of sin(x) for k=10.
d) Draw sin(x) using my_sin for x from 0 to 2pi with the intervals of 0.1pi for
k=1,3,5 and 7 in one plot.
