3) Write python functions to carry out the following summations; both functions can be in the same module (py file). In each case you should first prepare a flow chart, then write out the code by hand, and finally code it in Python. a) compute the following sum: s(n)=E Use the function to calculate the sum from 10 terms, 20 terms and 100 terms. Do you see it is heading for a limiting value of approximately 1.202 when N is sufficiently large? b) Modify the function from part a) to approximate the more general sum: 5(x)=E
