WOLFRAM LANGUAGE TUTORIAL
You can enter complex numbers in the Wolfram Language just by including the constant I, equal to . Make sure that you type a capital I.
If you are using notebooks, you can also enter I as by typing EsciiEsc (see "Mathematical Notation in Notebooks: Numerical Calculations"). The form is normally what is used in output. Note that an ordinary means a variable named , not .
This gives the imaginary number result
This gives the ratio of two complex numbers.
Here is the numerical value of a complex exponential.
|x+I y||the complex number |
|Conjugate[z]||complex conjugate or |
|Abs[z]||absolute value |
|Arg[z]||the argument in |
