Waves (in general)

Waves (in general). sine waves are nice other types of waves (such as square waves, sawtooth waves, etc.) can be formed by a superposition of sine waves - this is called Fourier Series . This means that sine waves can be considered as fundamental . Waves (in general).

Human Growth: From data to functions

Human Growth: From data to functions. Challenges to measuring growth. We need repeated and regular access to subjects for up to 20 years. Height changes over the day, and must be measured at a fixed time.
