| **The Linear expression**

Hi

I'm trying to understand the difference between the linear function and the ease function in After Effects but in terms of programing , I know that the ease function works like the linear but with easing the curve with a bezier.

And I know that the formula for the linear is

Y = ( ( X - X1 )( Y2 - Y1) / ( X2 - X1) ) + Y1 (The Linear interpolation formula)

what I need is the formula for the ease function ,I need this because I'm using a software that does not have a built-in function for the linear and the ease (like After effects ), I've already did the code for the linear but I would like to get a formula for the ease.

Thanks
