Basic Examples (1)
Define 0 to be the default argument for a function 
:
| In[1]:= |
| Out[1]= |  |
represents an argument that can be omitted:
| In[2]:= |
| Out[2]= |  |
If the second argument is omitted, the default value of 0 is used instead:
| In[3]:= |
| Out[3]= |  |
If both arguments are omitted, both are taken to have the default value 0:
| In[4]:= |
| Out[4]= |  |
