    Previous Value for Goals

      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.
