Trigonometry If you know a side and an angle of a right triangle, then you can find out a lot about the triangle. This is how trigonometry was invented. Trigonometry used to be a separate class in high school. Now we learn part of trig in Geometry, some more in Algebra 2, and more in Pre-Calculus.

5
Be happy you have Calculators!

6
Trig has 3 basic units Focuses on different ratios to help you find missing parts of triangles. These ratios are known as: Sine, Cosine, Tangent

Find each ratio Sin A= Cos A= Tan A= Sin B= Cos B= Tan B= C A B

12
Sin X= Cos X= Tan X= Sin Y= Cos Y= Tan Y= Find each ratio Y X Z

13
Sin M= Cos N= Tan M= Sin N= Cos M= Tan N= Find each ratio Q N M

16
We often know what the Angles are.

17
Some people are EVIL! Check to fix your calculator. Should say “deg” for degrees. If is doesn’t you are likely to get all the questions wrong.

18
Solve for x. 1.Is it sine, cosine, or tangent? 2.Set up the equation 3.Solve 4.Round

19
Solve for x.

22
Solve for X.

30
When you need to find the angle. 1.Set up the equation 2.Hit the “2nd” key and type sin then the fraction (or decimal some calculators are tempermental about fractions in the trig functions) 3.Make sure to close the parentheses

31
