SUMMARY
The area between the polar curves defined by r=4sin(θ) and r=2 is calculated using the formula for the area under a polar curve. The correct integral setup involves integrating from the intersection points of the curves, specifically from π/6 to 5π/6 for the outer curve and from 0 to π/2 for the inner curve. The final area is determined to be (10/3)π after evaluating the integrals. The discussion highlights the importance of correctly identifying the limits of integration based on the intersection points of the polar curves.
