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. The information about how r ...
A set of vertices S of a connected graph G is a nonseparating independent set if S is independent and G–S is connected. The nsis number 𝒵(G) is the maximum cardinality of a nonseparating independent ...
