Learn how to write the trigonometric equation of a graph step by step by identifying the key features that shape sine and cosine functions. You’ll see how to find the amplitude, period, midline, phase ...

have the same curve only shifted along the x-axis have an amplitude (half the distance between the maximum and minimum values) of 1 have a period (size of one wave) of 360˚ ...

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 been ...
