Method 1: Define the values beforehand:
![[Graphics:../Images/index_gr_32.gif]](../Images/index_gr_32.gif)
![[Graphics:../Images/index_gr_33.gif]](../Images/index_gr_33.gif)
![[Graphics:../Images/index_gr_36.gif]](../Images/index_gr_36.gif)
Use Simplify with any appropriate restricitons on the domains involved to reduce this.
WARNING: Use Clear to "unassign" this value from x or you can get into real trouble
