Difference between Sine, Linear and Quadratic animations?

What's the difference between these animation types?

[tildearrow]

The difference is that Quadratic/Sine look much smoother than the stock Linear animation curve. You can prove this by maximizing/restoring windows.

But what exactly does Quadratic do different than Sine?

[tildearrow]

The difference is that Sine feels slightly less stiff than Quadratic on higher animation speeds.

This is the curve for Sine:

This is the curve for Quadratic:
