Transformations of Functions - Graphing Sine and Cosine Example

In this video I go through a very useful example on how to graph a sine function using the principles of transformations, such as vertical and horizontal translations and stretching. I also show how you can easily switch between graphing the cosine and sine of a function using the simple trigonometric identity sin(x +pi/2) = cos(x). I go through in extreme detail in a step by step method on how to graph it so make sure you watch this video because it is pretty much the only example you are going to need on graphing sine and cosine functions!

I don't always graph cosine and sine functions but when I do I usually graph them manually to illustrate transformations ;)
