9-1

In this section we learned how to find the sides and angles of a triangle. This involved the use of a little thing called SOHCAHTOA. This stans for Sin=Opposite/Hypotenuse. Cosine=Adjacent/Hypotenuse, and tangent= opposite/adjacent. If you invert these you can also find out how to use cosecant, secant, and cotangent. I don't know when I will ever use this outside of school but I'm not gonna complain because this may be the easiest thing we have done so far this year. The steps are simple and the formulas are easy to remember because of SOHCAHTOA. So basically you are given a right triangle and a combination of side lenghts or angles. Then depending on what you are given you must find out the rest of the information required to get the answer.
