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