# Exclusions

 Exclusions is an option that specifies where to exclude in regions used by functions like Plot, Plot3D, and NIntegrate.
• The following settings can be given:
 None exclude nothing True exclude subregions associated with discontinuities {x1,x2,...} exclude specific points lhs==rhs exclude a subregion defined by an equation {lhs1=rhs1,lhs2=rhs2,...} exclude several subregions defined by equations {{lhs1=rhs1,ineqs1},...} exclude subregions defined by equations and inequalities
• For a region defined by n variables, excluded subregions must be of dimension .
• Exclusions->True excludes all subregions where discontinuities are found in functions being plotted. The discontinuities can involve either finite or infinite jumps in function values.
• Exclusions excludes subregions defined by a single equation and any combination of inequalities.
• Exclusions->{Automatic, {lhs1==rhs1, ...}, ...} excludes both subregions found automatically and specified explicitly.
• For plotting functions, ExclusionsStyle specifies how to draw excluded subregions and their boundaries.
Exclude portions of a surface where it has jumps:
Leave the surface entirely connected:
Exclude portions of a curve where it has jumps:
Exclude a fixed set of points:
Specify where the function is discontinuous:
Exclude portions of a surface where it has jumps:
 Out[1]=

Leave the surface entirely connected:
 Out[1]=

Exclude portions of a curve where it has jumps:
 Out[1]=

Exclude a fixed set of points:
 Out[1]=

Specify where the function is discontinuous:
 Out[1]=
