1.2: 4, 5, 7, 14
1.3: 11
1.5: 1, 5, 7, 9, 11

For 1.5 questions 9 and 11, demonstrate the same using matlab.

For question 9, plot the error for the Taylor series approximation of
degree 4 for values in the interval 0.25:0.01:1.

For question 11, and for the maximum error of 10^-4 in the interval
[1/2,1], plot the error of the Taylor series approximation for the the
following cases, i) the smallest order n* for which you do not get a
maximum error greater than 10^-4 and ii)  n*-1 for which you start
seeing errors greater than 10^-4.

For both matlab-based hws, please provide hardcopies of the source code
and plots demonstrating the error over the corresponding intervals (for
problems 9 and 11 above).
