The class Trigonometry: Sine, Cosine, and Tangent discusses the three basic ratios that are the basis for trigonometry. Trigonometry is based on the specific relationships between the sides and angles ...

Sine (sin θ): The ratio of the length of the opposite side to the hypotenuse (O/H). Cosine (cos θ): The ratio of the length of the adjacent side to the hypotenuse (A/H). Tangent (tan θ): The ...

Let’s look at how to use trigonometric identities to calculate missing sides. \({sin~θ} = \frac {opposite} {hypotenuse}\) \({cos~θ} = \frac {adjacent} {hypotenuse ...

An inverse function takes the output and does the opposite to get back to the input. The cosine (cos ... the opposite to get back to the input. The tan function takes the angle Ɵ and gives ...
