0 (in a triangle that has one angle of 90°) the ratio of the length of the side next to an angle less than 90°, divided by the length of the hypotenuse (= the side opposite the 90° angle)
1 in a triangle that has one angle of 90°, the ratio (= relationship) of the length of the side next to an angle less than 90°, divided by the length of the hypotenuse (= the side opposite the 90° angle)
This cosine function allows the coplanar influence to propagate to near-coplanar orientations, thereby allowing surface completion to occur around smoothly curving surfaces.
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.
In the same way, we can compute sine and cosine series.
Equation 3 shows the cosine correlation, one of the more common vector-space matching functions.
When running the experiments, a trajectory consisting of a combination of sines and cosines at different frequencies is selected.
Figure 6 shows the cosine of the characteristic angle measured relative to the top surface, as a function of disturbance frequency.
Operations required for the computation of sine, cosine, and () functions are not taken into account.
Note that for continuity u2 must be expressed as a sine, if cosines are employed for the other two velocity components.
