0 (in a triangle that has one angle of 90°) the ratio of the length of the side opposite an angle less than 90° divided by the length of the hypotenuse (= the side opposite the 90° angle) -- 正弦
For a subset of neurons in our sample, we measured visual responses to a drifting sine-wave grating.
Therefore, in the second experiment, we measured temporal tuning functions of cor tical neurons using drifting plaid patterns (or thogonal contrast modulated sine-wave gratings).
The miner progressive cross track deviation can be calculated as the integral of the sine of heading deviation with respect to along track distance.
It is, in a way, the sine qua non of municipal connections, since it gives them grandeur and legitimacy.
The purest form of sound for the ear is a sine wave, which mathematically is a continuously varying trigonometrical function.
Subjects favored a sine wave path over the parabolic trajectory, and generally all paths of some continuous curvature were judged to be fairly natural.
Additional columns are added for a constant term, and for sine and cosine sequences at the mains electrical frequency, to fit contamination from this source.
The initial excitation is composed of two sources - a pulse oscillator and a frequency-modulated sine oscillator.
