NCEA 3 Calculus Exam 2022, Complex Numbers How I'd Answer

 Here is how I'd answer the complex section of the exam. 

I don't use complex numbers in my professional life as a mathematician. This means that every time I teach this, I have to teach myself all over again how to do complex analysis, going over my university calc notes. 

This is another good reason to keep clear and concise notes--you may need to use them yourself years later!

You will use complex analysis in a range of technical fields including engineering and electrical fields. 

I do use the closely related field of linear algebra all the time, and it is very likely that you'll need to use linear algebra if you go into a technical field. 

Anyway, if I made a mistake please let me know.
