You can enter complex numbers in Mathematica just by including the constant I, equal to . Make sure that you type a capital I


.




  • This gives the imaginary number resultĀ 


    .
  • In[1]:= Sqrt[-4]

    Out[1]=

  • This gives the ratio of two complex numbers.
  • In[2]:= (4 + 3 I) / (2 - I)

    Out[2]=

  • Here is the numerical value of a complex exponential.
  • In[3]:= Exp[2 + 9 I] //N

    Out[3]=
