WebJan 2, 2016 · a shifted sine is a linear combination of a sine and a cosine. For specific values of the shift, one of the terms vanishes. For example, sin ( x + π 2) = cos ( x). For π / 4, the terms get the same amplitude, sin ( x + π 4) = 1 2 ( sin ( x) + cos ( x)). More generally, a sum of sinusoids and cosinusoids with arbitrary amplitudes can always ...
