Simple examples

In[1]:= Im[1]
Out[1]= 0

In[2]:= Im[0.5]
Out[2]= 0

In[3]:= Im[(2)/(3)]
Out[3]= 0

In[4]:= Im[2 + I]
Out[4]= 1

In[5]:= Im[(1*E^(I*(Pi)/(4)))/(2)]
Out[5]= (1)/(2*Sqrt[2])

In[6]:= Im[(I*-1)/(Sqrt[2])]
Out[6]= (-1)/(Sqrt[2])

In[7]:= Im[a*I*b]
Out[7]= Re[a*b]

In[8]:= Im[(I)/(Sqrt[2])*-1 + (1*E^((I*Pi))/(4))/(2)]
Out[8]= (1)/((2*Sqrt[2]))*-1
