Ground rules for homework: if necessary, you can get help from any source (friends, classmates, books, the web) but you

If you have any questions about homework, please email me, not the grader. Also, you may send questions to the class mailing list, and suggestions for trouble-shooting (but not homework solutions!) may be posted there too.

Exercises from my book: Ex 6.4, 6.8, 7.1, 7.2, 7.4, 7.5, 7.6, 7.8, 11.1, 12.1, 12.7, 13.3, 13.4. Even if the exercise does not call for this, explain why your answers make sense!

For Ex 11.1, you can modify the C program which is here, or you can rewrite it in Matlab. You don't need to include the program listing, just the results.

For Ex 13.4, use the following clarification. For part 1, you don't need to refer to Ex 12.3; instead refer to the Taylor expansion of exp(x) on the next page. For parts 2 and 3, it's easier to use Matlab instead of C and to combine these parts together. The question is whether computing f(x) by the statement "exp(x) - 1" is unstable, compared to using the function
