@markleeds Because otherwise sin(2*pi*t) = 0 or all integer t. I realize this isn't the case here, but I am in the habit of putting a non-zero phase offset on my cos and sin terms. I've been caught too many times finding wonderful things happening, only to have them fall apart because of the phase offset not being zero.
