(a) Find the limit of {(1/(n^(3/2)))-(3/n)+2} and use an epsilon, N argument to show that this is indeed the correct limit. (b) Use an epsilon, N argument to show that {1/(n^(1/2))} converges to 0. (c) Let k be a positive integer. Use an epsilon, N argument to show that {a/(n^(1/k))} converges to 0. (d) Show that if {Xn} converges to x, then the sequence {Xn^3} converges to x^3. This has to be an epsilon, N argument [Hint: Use the difference...

If S = 1-x/1! + x^2/2! - x^3/3! + ..... where n! means factorial(n) and x is a variable that will be assigned. Use matlab to compute S for x = 7 and n (number of terms) = 5. Write the value below as the one displayed when you issue "format short" in matlab. Explain the process and result of the question.
