Homework assignments will usually be posted a week before they are due (generally on Wednesday). A subset of the underlined problems will be graded; if a problem is not underlined it is recommended and/or may be good for practice, but need not be handed in. Point values for graded problems will be posted here after assignments are collected, and solutions will be posted on CANVAS.
Recommended homework_guidelines.pdf for formatting your homework solutions (from a previous class, hat tip to Victor Camacho).
