WebFor areas in rectangular coordinates, we approximated the region using rectangles; in polar coordinates, we use sectors of circles, as depicted in figure 10.3.1. Recall that the area of a sector of a circle is α r 2 / 2, where α is the angle subtended by the sector. If the curve is given by r = f ( θ) , and the angle subtended by a small ... Web1. r = 3 sin 5 θ, r = 3 sin 2 θ r = 1 – 3 sin θ, r 2 = 25 sin 2 θ The polar curves of these four polar equations are as shown below. Match the polar equations with their corresponding polar curve. 2. Test whether r 2 = 16 sin 2 θ is symmetric with respect to the polar axis, the line θ = θ 2, or the pole. 3.

WebGraphing. In mathematics, a graph is a representation of a set of objects where some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called "vertices" or "nodes", and the relations between them are represented by mathematical abstractions called "edges" or "arcs".
