6. It is known that the series Sn 1+2+3+...+n4 converges to for no. Use MATLAB to study the convergence of the series. a) Write a MATLAB script that evaluates the first terms of the series numerically. The script prints the values of Sn. S-5 and 1(905) /4 for n=1,2,..., N where N is a reasonably chosen upper limit. b) How many terms of the series are necessary to obtain an approximation of with 5 significant digits? How many are required for 6 significant digits?
