Four Bar Linkages 1

[antd]

I am currently working on a system using a four bar linkage.
I want to create a spreadsheet that will calculate the movement of the linkage.
Has anyone got the equations that i need to do this.

I think you'll find Pythagoras is all you need, if you are working in the time domain.
