(Odd) Rose AreaSlider "a" is a magnification tool and Slider "theta" is the theta value and is used to change the point P on the curve (and subsequently the area). The area is computed for the portion of the red curve that is bounded by line segment PQ. Slider "f" changes the number of petals on the rose. Remember you can utilize symmetry to find the total enclosed area!
