sine wave

Sinusoidal waveform A waveform of periodic oscillations–eg, in alternating current in which the amplitude of each point in the wave is proportional to the sine of the time from a start point Cardiology An EKG finding described in severe hyperkalemia where the 'P' wave disappears and the QRS complex and 'T' wave merge in an oscillating pattern

sine wave

(sīn wāv)
A symmetric wave representing one complete cycle of a single-frequency oscillation; the displacement of mass over time described by using a function from trigonometry, the sine.

The value of sin(x) is almost equal to x during this interval, and therefore the linear segment has been fitted precisely to the sine curve. Beyond this point, the SFDR is decreased until reaching the lowest level at [beta] = [pi]/2.
To show the contribution of the linear segment, the residual error of the approximated sine curve, based on one segment fourth-order approximation, is also shown (dashed red line), with MAE equals 2.2 x [10.sup.-4].
The first sine curve was from [H.sub.min] to [H.sub.x] and the second from [H.sub.x] to [H.sub.max]; [D.sub.x] is the actual temperature at time [H.sub.x], while time H and temperature D define the points to be fitted.
However, in this case the period from the transition point may not be a sine curve so exponential and square-root decay functions were considered.
These results indicated that these supply operations maintained high states of readiness throughout the IDTC and avoided the readiness sine curve trough.
Additionally, the 112 CMP assist visits and 69 LLTTs were major factors in maintaining a "steady strain on the line" and reducing the trough in the logistics readiness sine curve. Spreading training over the entire IDTC and focusing that training as a result of CMP data reduced manpower expenditures and produced measured readiness improvements.
Neither of these results is unexpected, since we are dealing with sine curves (roughly speaking), which take much longer to turn the corner than pass through the midpoint.
In signal measuring and manufacturing, a sine curve wave could be gotten with filtering methods.
To have a better comparison, we also plot several representative pairs of ground truth backgrounds (the simulated sine curves) and the estimated ones obtained by different methods in Figure 3.
Obviously computer-generated music and the fractal equation may be introduced with the commencement of the study of calculus (sine curves, gradients) and after students have mastered algebra.
Sine curves and three-axis movement get very complicated.
Modifying the involute straight tooth spur gear with straight line, parabola and sine curves can improve the dynamic performance of gear drive [2].
