M5 Exercise
Instructions
1. Do exercise 6.3 on page 160 of the textbook.
o Submit an m-file named: hw5_ex1_LastName.m.
2. Modify your solution to last week’s exercise (poly_curv_fit.m) by implementing left division rather than explicitly implementing the least-squares matrix solution.
3. Do a variation on exercise 7.5 on page 177 of the textbook. Do not implement an indefinite-length series. Instead, implement a fixed-length series that terminates at the seventh-power term. Test it in the range of -3 < x < +3.
