One day I was walking down the street when a guy asked if I knew how to Graph the equations 

Y= sin 2p(x)  and Y=sin p(x), and if I could he would give me ten dollars.

This problem is easy to me because I was taught it by The BWELL.  Here is how she taught me.

1) The first step to solving this equation is to draw your graphs axis.

2) Next you determine the type of equation you are graphing. in this case it is sin.  This means 
that you will be starting the graph at 0.

3) Then you figure out the amplitude of the equation by the number which is before p. That is how many times the graph completes a cycle of up and down each p unit. 

4) Then you determine the size of the period. You do this by 360 by the number in front of the x.  Which in this case our period is 360 or 2p.

5)  Next you draw your graph.
