hi

first off , do you know how to sketch the graph of cos 1/2 Θ ?

Note that its period is 2π/(1/2)=4π

The usual graph we draw (cos Θ) has a period of 2π but this time , 4π .

|cos 1/2 Θ| - reflect the negative part of the graph to the postive side

- |cos 1/2 Θ| - reflect the whole graph about the x-axis

2 - |cos 1/2 Θ| - shift the graph up by 2 units . - May 5th 2010, 04:58 AMArchie Meade
