Final answer:
The inverse tangent of a complex number is called the Complex InvTan. It returns the angle (in radians) whose tangent is z.
Step-by-step explanation:
The inverse tangent of a complex number is called the Complex InvTan. It is denoted as ComplexInvTan(z) or atan(z), where z is the complex number. The Complex InvTan function returns the angle (in radians) whose tangent is z. It takes two arguments, the real part (x-coordinate) and the imaginary part (y-coordinate) of the complex number.
