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 ...

An object is moving counter-clockwise along a circle with the centre at the origin. At \(t=0\) the object is at point \(A(0,5)\) and at \(t=2\pi\) it is back to point \(A\) for the first time.

Anyone who’s taken classes in geometry, algebra, trigonometry or other advanced math forms has certainly encountered the graphing calculator before. These multi-function devices make incredibly ...
