Hi I hope someone can either help me directly and give me an overview of what needs to be done and also direct me to a textbook or some source which will allow me to learn this in depth.(adsbygoogle = window.adsbygoogle || []).push({});

Basically If I have data and I graph it, I fit a line to it (it can be curved) how then do I determine an equation to represent that line and allow me to extrapolate.

For example if the line is sinusoidal or straight and then beginning to curve etc how can I make a mathematical model to represent these different types of curves.

Thanks very much,

R
