Right Triangle Trigonometry
This week we will be taking a look at right triangle trigonometry. For this unit I highly encourage students to have a traditional scientific calculator, as opposed to using their iPad. As I have mentioned earlier, different calculators require different keystrokes for trigonometric ratios. It is best if students get to know a traditional calculator that they would use on a standardized test such as an ACT.
We will start the week by talking about the three basic trigonometric ratios: sine, cosine and tangent. We will then use these ratios to solve for missing side lengths and missing angles. We'll discover that if we know only a little bit of information about a right triangle's angles and sides, we can figure them all out!
We'll be able to figure things out, like how tall the building is that is drawn on the left, just by applying our knowledge of trig ratios. The knowledge of trig ratios will set up for success in Algebra 2 and beyond.
If you have trouble with the content, please come see me for some extra help. I am available most days before school and after school. I am also in the media center every Thursday during AO (7:20-7:50).
