;y = o. 246 Elementary Calculus. Referring a, expressed in radians to the #-axis, andusing the same scale as the ordinate, we obtain a sinuousor wavy curve, known as the Curve of Sines or the Har-monic Curve. If the motion of the point giving rise tothis graph be made quicker or slower, the… … Fig. 18a. method; the student should have no difficulty in understand-ing the principle after an inspection of the figure. It willbe noticed that the curve does not begin upon the x-axis,but that the periodic time is counted from the instant thatthe point Pt has passed through the angle e. This…
