Algebra III Trigonometry

Go to IXL.com, choose MATH, choose PRECALCULUS, go to sections M, N, & O. There are 30 skills under these 3 sections, you need to do them all - start with M.1 and go in order from there.

We will count a smart score of 80 as a 100%. If you can do all of those without whining (by date tba), we'll call Trigonometry finished and move on with no test! You will need to do at least 1 section per day - don't procrastinate and try to do them all at the end - it will be too much!
