Let's test it:

For example, this module can help with some math function:

• simple linear tweening - no easing, no acceleration;
• quadratic easing in/out - acceleration until halfway, then deceleration;
• cubic easing in/out - acceleration until halfway, then deceleration;
• quartic easing in/out - acceleration until halfway, then deceleration;
• sinusoidal easing in/out - accelerating until halfway, then decelerating;
• ...
