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 ...

Abstract: A graph G is conditional k-edge-fault Hamiltonian if it remains Hamiltonian after deleting at most k edges and each vertex incident to at least two nonfaulty edges. A graph G is k-edge-fault ...
