Use a sheet of graph paper to draw a sketch of the exponential function with the assistance of a graphing calculator. Then, find the value of f(2) for the function.

Which approach, Jaccard or Hamming distance, is more similar to the Simple Matching Coefficient, and which approach is more similar to the cosine measure? Explain. (Note: The Hamming measure is a distance, while the other three measures are similarities, but don’t let this confuse you.)

This exercise compares and contrasts some similarity and distance measures.
