Non-linear physics is the study of systems where the output is not directly proportional to the input. Unlike linear systems, which follow simple, predictable relationships, non-linear systems exhibit ...

Six non-linear growth functions were fitted to tree height-diameter data of ten conifer species collected in the inland Northwest of the United States. The data sets represented a wide range of tree ...

Expansions of typically encountered non-linear functions Ah, well, you might say, so the coefficients of cos (3ωt) in the expansions of cos n (ωt) might be significant, but the power series expansions ...
