Simple Harmonic

This curve is also one of the discontinuous curves that easily causes vibration, but since it has smooth and good
(low) properties, it can be used for low speed applications. When this curve is used for no-dwell applications,
(out & back) the discontinuity of acceleration at the starting and end points is not a factor and then this curve is
regarded as the best curve for no-dwell use. The modified sine curve is considered an improvement over the
simple harmonic.
