| Function | Description | 
|---|---|
| Bell (center, height, width) | Returns the Gaussian(normal distribution) function, also known as a bell-shaped or bell curve, based on the center time, height and half-height-width of the curve. | 
| EaseIn (start time, end time) | Returns an increasing Hermite-like transition S-curve between two given times. | 
| EaseOut (start time, end time) | Returns an decreasing Hermite-like transition S-curve between two given times. | 
| Sinus (period, amplitude,offset) | Returns a sinus profile curve based on the given period, amplitude and offset values. | 
| Square (period, amplitude,offset) | Returns a square profile curve based on the given period, amplitude and offset values. |
