Late submission is subject to automatic 20% reduction. • When submitting, make sure you upload your matlab or python codes, in addition to your answer sheets to analytical questions. Topic: Differentiation Consider numerical differentiation schemes using a. - f(x0-2h)+ 4 f(x0-h) -3 f(x0) b. f(x0-h) - 2 f(x0) + f(x0+h) c. f(x0-2h) - 8 f(x0-h) + 8 f(x0+h) - f(x0+2h) d. -f(x0-2h) +16 f(x0-h) -30 f(x0) + 16 f(x0+h) - f(x0+2h) These are the same as Quiz no.7 For each scheme, 1. [5pts] identify the order of derivative 2. [5pts] Identify the order of truncation error 3. [10pts] Write a matlab or python code that gives the corresponding derivative at arbitrary x0 any h 4. [20pts] For f(x)=exp(2x), a. obtain analytical form of corresponding derivative at arbitrary point x b. At x0=0, obtain expected numerical value of the corresponding derivative c. Generate a figure equivalent to Fig.14.2 in the text book d. Comment on the figure. Bonus Points: Quiz 6. Data Fitting Using Normal Equation Indicate your choice: A. Redo Quiz 6, and submit a new one B. Keep original submission/points of Quiz. Full points correspond to 2% towards final grade either way.
