How to solve sin cos tan without calculator

WebFeb 23, 2015 · The first step is to stop and think about the problem itself. What is the cosine? If you recall, the formula for cosine (remember SOHCAHTOA?) is adjacent over hypotenuse. So, with your $\frac{1}{3}$ example, $1$ represents the length of the adjacent side, and $3$ represents the hypotenuse. WebSin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is …
