To sketch the graph of a polar equation a good first step is to sketch the graph in the Cartesian coordinate system. This will give a way to visualize how r changes with θ.

Figure 4.3.2. Graph of r=1+3cos(2θ)? r = 1 + 3 cos (2 θ)? Consider the curve given by the polar equation r= 1−2sinθ, r = 1 − 2 sin θ, for 0≤ θ<2π. 0 ≤ θ <2 π. Find the Cartesian coordinates for the ...

Math students at Indus High School are solving linear equations and graphing ordered pairs of points on a life-sized Cartesian plane. The grid is composed of nearly 10,000 poplar trees, planted in … ...
