Homework: (all from textbook)

You don’t need to print your codes with the homework. Just print the outputs.

 

HW1 (due Thursday, February 13):

sec 1.2: 5(a)(b). (ignore things about relative errors)

sec 2.1: 3, 18. (you could use my codes, but you are suggested to write your own. Intermediate values of p_n should be shown in your report.)

sec 2.2: 5, 12    (for 12, you could use a code with TOL much smaller than 10^{-4}. Ignore the last sentence in the problem.)

sec 2.3: 6(a) (Intermediate values of p_n should be shown in your report)

 

HW2 (due Thursday, February 20):

sec 2.3: 11(b) (only Newton’s and secant methods)

sec 2.4: 10 (this result means, if you know the multiplicity of the root you want to find, then you can achieve quadratic convergence without computing f”(x) (like in the modified Newton’s method))

sec 3.1: 1(a)(c) (for the polynomial with deg<=1, use any two base points out of x0,x1,x2)

 

HW3 (due Thursday, February 27):

sec 3.1: 3(a)(c) (only for degree-2 case)

sec 3.2: 1(a) (you are suggested to write a code because this is a nice practice of coding)

sec 3.3: 1(a)

 

HW4 (due Thursday, March 12):

sec 6.2: 1(a)(d), 3(a)(d) (you are suggested to write your own code, as practice)

sec 6.6: 2 (only the ‘strictly diagonally dominant’ part)

sec 6.5: 2(a), 6(a)(d)

 

HW5 (due Thursday, April 2): (you are supposed to submit via ELMS)

sec 6.6: 3(a)(b), 17

sec 8.1: 3

 

HW6 (due Thursday, April 9): (you are supposed to submit via ELMS)

sec 8.2: 1(a)(c), 11          (weight function w(x) is constant 1 if not stated in the problem)

 

HW7 (due Thursday, April 16): (you are supposed to submit via ELMS)

sec 4.1: 1, 5(a)(c), 28

sec 4.2: 8

 

HW8 (due Thursday, April 23): (you are supposed to submit via ELMS)

sec 4.3: 1(c), 3(c), 5(c), 7(c), 23

sec 4.7: 1(a)

 

HW9 (due Thursday, April 30): (you are supposed to submit via ELMS)

sec 4.4: 1(c), 3(c)

sec 5.2: 1(a), 3(a), 6(a)      (I will give a concrete example of Euler’s method on April 28’s lecture)

———————-HW9 is the last homework———————-

Suggested problems: (not required to submit)

sec 5.3: 6(d)

sec 5.4: 1(a), 5(a), 13(a)

sec 5.6: 4(a) (only 4-th order A-B method), 17

sec 5.9: 1(a), 3(a) (both using midpoint and modified Euler methods)

 

Homework still uses 10th edition textbook (available here https://drive.google.com/file/d/1Q8r1C_GUegqJBpd_3moTHzt3qv5qxc-v/view)
