What we learned in class today was how Angles could be viewed by different ways on how people may look at it. I learned that ANGLES OF DEPRESSION is a type of shape if you were to view it looking downwards, it doesn't matter where you look there always seems to be a shape. Also another type of angle i learned in class was ANGLES OF ELEVATION, how you may see an angle just be looking up or at the sky, there would always seems to be a shape no matter how you see it.
For Triangles i learned how SOH CAH TOA is used :
Sin = Opposite over Hypoteneuse
Cos = Adjacent over Hypoteneuse
Tan = Opposite Over Adjacent
For Some of the slides in todays assignment, i learned how to get the value of the ratios
a.) Sin 45 = 0.7071 ( you type in your calculator "sin" and the number then equals)
Same thing goes with the rest of the work we also did that relates to trigonametry

What I learned in this unit was that spreadsheets is an easy way to use formulas, and organize numbers. I learned that spreadsheets have labels and different types of values. Not only could we put numbersand the different equations but also, we can use Formulas to resolveeach cell. I also learned different types of math tricks in mental mathsuch as when a number is multiplied by 9 you use an easier trick by comparing it by 10.
Examples For Forumlas :
=SUM (B4*B5)
=AVERAGE (D6*D7)

What we learned in class today, was how to use some techniques in Spreadsheets. It's interesting because the spreadsheets that we used was a lot different from the other spreadsheets we usually use. I also learned how to make a new page on http://cm20sf07.pbwiki.com; Not only do we have our own page as a class, but we also could put our assignments, and we can make our own spreadsheets. We may edit it and publish it so other people may see it. I also learned how to get answers on using basic Formulas to figure out the result of an equation more easily.
For example:
= Sum (B3:D3)
=Average (A1:A11)
