1. A mathematical sequence whose terms alternate between increasing and decreasing, or fluctuate around a central value without converging to a single limit
The sequence 1, -1, 1, -1, 1, -1... is a simple oscillating sequence that never converges.
A sequência 1, -1, 1, -1, 1, -1... é uma sequência oscilante simples que nunca converge.
2. In physics and engineering, a sequence of values that exhibit periodic or quasi-periodic fluctuations
The oscillating sequence of voltage measurements indicated an unstable circuit.
A sequência oscilante de medições de tensão indicou um circuito instável.
This is primarily a technical term used in mathematics, physics, and engineering education. It is used identically in both Brazilian and American academic contexts, though some European Portuguese speakers may prefer 'sequência oscilatória'. The concept is fundamental to understanding limits, convergence, and wave behavior in STEM fields.
