In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has ...

The angle between VC and the plane is \(y\). It is not possible to use trigonometry to calculate the angle \(y\) because the length of another side is required. Pythagoras can be used to calculate ...
