Define a tent map by


where , ; has a maximum at .

Let be the function composed with itself times and let be the number of intervals over which is monotone; for the tent maps considered here, is twice the number of maxima of .

Define the entropy to be .

For the tent map with maximum at , the entropy of is 1, as the number of maxima is .
