HOMEWORK ASSIGNMENT 3 EGM 3344 Numerical Errors & root finding Due: Friday, Sept. 24 Problems from Chapra book chapter 4 For all of these problems, feel free to use a simple Matlab program to calculate function values (like using a calculator) when the indicated approach is by hand. Problem Approach Comments 4.1 Hand Hint: First number is an integer, second number is a floating point. Write out solution equation by hand. Do calculations in Matlab if desired. 4.3 Matlab Name your Matlab program macheps.m 4.4 Matlab Skip the challenge question. 4.7 Hand Only do 3-digit arithmetic part. Write out all equations by hand and use Matlab or calculator for intermediate results. Chopping means truncate to only 3 digits after each intermediate calculation step. 4.12 Hand 4.15 Matlab Evaluate the remainder term in the Taylor series at x = 2 to estimate t E 4.21 Matlab Study the code on pp.105-106. S1 hand See problem and notes below this table. S1. (Nested form) Evaluate f(x) = x 3 - 7.5x 2 + 11.2x + 2.8 = ((x - 7.5)x + l l.2)x + 2.8 at x = 3.94 using 3 significant (3S) arithmetic and rounding, in both of the given forms. The latter, called the nested form, is usually preferable since it minimizes the number of operations and thus the effect of rounding.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
