Analytical models of phenomena ( equations from physics) Create an equation from observed data 1) Interpolation (connect the data-dots)If data is reliable, we can plot it and connect the dotsThis is piece-wise, linear interpolation This has limited use as a general function Since its really a group of small s, connect
