Frequently asked questions
- What is the difference between continuous and annual compounding?
- Continuous uses e^(rt); annual uses (1+r)^t. For small r they are close, but continuous growth is slightly faster and is the standard in population biology.
- Can growth rates be negative?
- Yes — a negative rate models population decline or any shrinking quantity.
