To solve the equation
, we start by isolating
:
Now, we’ll express
in polar form. The modulus is
and the argument is
(since -i corresponds to this direction):
To find the cube roots, we use the formula for roots in polar form:
Here,
,
,
, and
.
Calculating:
-
- Angles for
: - For
: - For
: - For
:
- For
Thus, the solutions are:
So the correct answer is:
A.
Finding roots in the complex plane can feel a bit like a treasure hunt! Each solution is like a unique clue leading us to different corners of the mathematical map. The roots you find aren’t just numbers—they represent their own unique stories in the realm of complex analysis!
If you’re interested in diving deeper into complex numbers, try exploring De Moivre’s theorem or polar coordinates further! These concepts will enhance your understanding and will give you tools for tackling even more complex equations.
