Hi sir, just have two questions.

I first applied z1*z3 then divided the result by z2. I assume this is okay since it yields the correct answer.

And also doesn't the value of -Pi lie outside the range of the principal argument, it gets the same result but should it not be -Pi+2pi = Pi, since that lies inside the range of the principal argument.

Thanks.
