NettetArea = x dy 0 b = 0 a2 − y2 dy We don’t yet have a rule for integrating functions of this form. Considering that this integral arose from a question about a circle, it’s not surprising that trigonometry will play a role in its solution. When working with circles it often helps to use polar coordinates. In this Nettet13. jun. 2024 · Integrating the Area of a Circle. So I understand that the circumference of a circle is represented by the expression 2 π r, and integrating it yields the area of the circle, represented by the expression ² π r ² - which also corresponds to the area under …
NettetWhat you found was the arc length or circumference of the circle. To become the area take the integral ∫ ds dr. Because for a small arc length ds times a small distance dr you become a rectangle. Some all rectangles up and you get the area of it. Remember that ds was your first Integral ∫ r dθ.
