Work Step by Step

Biorhythm cycles modeled by sinusoidal graphs should be useful for most of the people because most of us live with a certain lifestyle which can be described by the graphs. For example, we may get up at 7am, have breakfast, work for 4 hours, have lunch, work for another 4 hours, have dinner, go to bed at 11am, and repeat the same pattern day after day, thus generating a lifestyle pattern which can be simulated using sinusoidal graphs.
