16 Νοε 2022 · In this section we will discuss how to the area enclosed by a polar curve. The regions we look at in this section tend (although not always) to be shaped vaguely like a piece of pie or pizza and we are looking for the area of the region from the outer boundary (defined by the polar equation) and the origin/pole.

Let R be the region that is inside the graph of r = 2 and also inside the graph of r = 3 + 2 cos q, as indicated above. Find the area of R. A particle moving with nonzero velocity along the polar curve given by r = 3 + 2 cos q has position (x(t), y(t)) at time t, with q = 0 when t = 0.
Math 20B Area between two Polar Curves. Analogous to the case of rectangular coordinates, when nding the area of an angular sector bounded by two polar curves, we must subtract the area on the inside from the area on the outside.
(a) Give the formula for the area of region bounded by the polar curve r = f( ) from = a to = b. Give a geometric explanation of this formula. (b) Give the formula for the length of the polar curve r = f( ) from = a to = b. (c) Use these formulas to establish the formulas for the area and circumference of a circle.
The trick with polar graphs is to be careful with what interval it takes to trace out the polar graph. Watch what happens with this example. Find the area bounded by 5 sin . Find the area of the shaded region of the polar curve for. [you have to be able to figure out that the boundary is 0 to pi.] cos 2.
Example 9 A polar curve is defined by the equation 𝑟=𝜃+sin(2𝜃) for 0≤𝜃≤𝜋. a) Find the area bounded by the curve and the x-axis. b) Find the angle 𝜃 that corresponds to the point on the curve where 𝑥=−2.
