Graphs of Sine and Cosine 1.2 An applet illustrating how the graphs of sine and cosine are related to the unit circle. Transformations of Functions 1.3 An applet illustrating how transformations ...

The cosine (cos) function takes the angle Ɵ and gives the ... The correct trigonometric ratio is sin\(Ɵ\) = \(\frac{o}{h}\). Label the sides given. 12 cm should be labelled as hypotenuse ...

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 ...

Mathematicians had long thought that using trigonometry to prove the theorem was unworkable, given that the fundamental ...
