hello i am attempting to review basic in prob & am having problem understanding why a triangle wave has a distribution which is uniform. i am looking at the function shown in Triangle Wave -- from Wolfram MathWorld. In the picture, the frequence of 1 is 3, however the frequency of 0 is 6, therefore the distribution should not be uniform since 0 is encountered more frequently than 1 or -1. please let me know how i am thinking about this in the wrong way.
