Previous Value for Goals

Question asked by 1-S5Y8F6 on Oct 27, 2010

Hi,

 

Is there a way to obtain a change in value in an equation.

 

For example,

 

x = Surface Temperature of a Solid.

 

I want an equation to have x and the x at time t (where t is less than the time at current value) so I'm able to get a delta change value.
