There will also be a problem on trig, using the coordinate plane. Practice on the WeBWorK
“CoordinatePlaneTrig” problems.
Here are some resources for some of the other problems: also please see the relevant WeBWorK assignments, which will show you solutions to similar problems.
For problem 1, solving a 3 by 3 linear system:

Remember that if you get stuck on any of the problems or have a question about any of the material, you can post a question to the Piazza discussion board. I have posted several of the review problems so that you could post your solutions for a homework point if you wish. If you post by taking a photo (or better, a scan) of your work, please make sure that it is clearly legible.
Also, you may post a solution to any other problem from the review by posting the problem itself as a Question on Piazza and then posting your solution as the student solution to that question.
There are also several student questions which you could post a solution to if you wish.
Genius scan is a very nice app for taking scans with a smartphone.
