You can put this solution on YOUR website! Graph the function: y=4sin 2θ.
Sketch the sine curve on a coordinate system.
The "4" causes the top of the curve to be at (theta=45 degrees ,4).
That means the amplitude is "4"
The "2" causes the period to be 180 degrees instead of 360 degrees
so it crosses the x-axis at 0,90, and 180
Cheers,
