ExcludedForms

ExcludedForms

is an option that gives a list of patterns for expressions that should be excluded from an operation performed by a particular function.

Details

  • Different functions use different default settings for ExcludedForms.
  • In functions such as Simplify and FullSimplify, ExcludedForms specifies classes of expressions that should not be touched if they are encountered at intermediate stages in a computation.
  • In functions such as TakeLargest and TakeSmallest, ExcludedForms specifies classes of expressions that should be considered in selecting elements to return.

This gives no simplification:

In[1]:=
Click for copyable input
Out[1]=

Excluding transformations of (x-2)^10 allows you to expand the remaining terms:

In[2]:=
Click for copyable input
Out[2]=

This gives a result in terms of Arg[x]:

In[1]:=
Click for copyable input
Out[1]=

This specifies that Log[x] should not be transformed:

In[2]:=
Click for copyable input
Out[2]=
