What is complex conjugate of #i#?
It depends...
A conjugate of a number is a number that goes with it in the sense that multiplying the two numbers together yields a simpler kind of number.
For numbers involving radicals, we want to find a multiplier that results in a rational result. For complex numbers we want to find a multiplier that lead to a real result.
We find:
Using this convention, we find:
However, please note that this is not the only possible choice of conjugate.
For example:
Why do I stress this ambiguity?
So in general usage, it is conventional to stay with the standard complex conjugate and refer to "complex conjugate pairs" (for example).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
