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.

- Why is a cepheid variable star referred to as a standard candle?
- If a supernova happens when a giant star uses up its fuel, how are new stars created? If all the hydrogen is gone how would a new star emerge from the debris of a star that has used all its fuel?
