Let's replace cos( ) with sin( ) in the following equation:

Then we have the following equation:

As before, when cos( ) is replaced with sin( ), the graph is rotated /2k radians.


Examples




Conclusions:  Replacing cosine with sine

 

When cos( ) is replaced with sin( ) in the equation

we have

The graph is rotated /2k radians.
