Formula page

I expect that you will be able to use a formula page for this class,  but that will be determined by your teacher.

Your teacher may have a formula page they expect you to use.

Below is a link to the formula page I will use (at least for now!) when I’m doing questions for this class.

This may change, depending on feedback from your teacher.

I encourage you to download this page and print it so you have it handy when you are doing math.

Notes

Question 3,    I didn’t do a video for this one.
Your teacher may cover micrometers in more detail so you can do this question.

Question 4,    I didn’t do a video for this one.
Your teacher may cover calipers in more detail so you can do this question.

Question 6,    I didn’t do a video for this one.
If you did this with numbers it wouldn’t be too bad, but using algebra is really tough.
If you NEED to do this, your teacher can give you some help with the process.

Question 7,    I didn’t do a video for this one.
You may remember your trigonometry from a previous math class, but... since trig isn’t covered till the NEXT unit,  I decided not to do this.    If you NEED to do this, your teacher can give you some help with the process.
