### Lecture Notes and Suggested Homework

Most test and exam questions will be like some of the Suggested Homework and Assigned Homework problems. Make a serious attempt to solve Suggested Homework problems, before consulting the Student Solutions Manual. If you missed a lecture, this is an approximate guide to what topics were covered. Page and question numbers are from the new 11th edition. The same problems are in the 10th edition, but on different pages and sometimes with different numbers (so annoying!).

### Assigned Homework

Submit your Assigned Homework solutions ON TIME for marks. Homework is due at the beginning of the lecture on the due date. Homework submitted after the beginning of the lecture on the due date will not be marked. (We are expecting to set up a system where you submit your homework by uploading files, like photos of your written work, to a website. More information will be provided here when it's available.)

Put your NAME and UBC I.D. NUMBER in the TOP RIGHT corner of the ALL pages.
