(adsbygoogle = window.adsbygoogle || []).push({}); how do you find the trend in some functions??

ok so i'm not sure how to phrase the question, and i'm not sure it will help me anyway but...

if i have say 3 complex functions, and i weight them... can i find the function that follows the trend?

sorry if that's very basic or silly.

basically, i want to weight silence, a traingle wave, a square wave, and a sine wave according to some percceptual quality. i then want to, based on that weighting, calculate the function that best instantiates that quality. of course it won't be perceived like that, but is there a term for the mathematical function of finding the trend of a number of functions according to some weighting?

thank you for any help ha :)
