In a function such as sine or cosine, we could also have a translation ... This is when the graph of the function has been shifted to the left or right by \(a\) degrees. If you have: \(\sin ...

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