Growth is a very general feature of Template:Ency term and systems. It has however also quite diversified characteristics in different cases.
The following listing is a selection of the most useful growth curves related to specific types of processes:
1. Asymptotic: permanently slowing down growth
2. Chreodic: periodic (fluctuating) growth within a growth Template:Ency term
3. Exponential: permanently accelerating growth (i.e. explosive)
4. Lineal: constant arithmetic proportional growth
5. Logarithmic: Template:Ency term growth defined by a characteristic exponent
6. Logistic: an accelerating growth phase preceeding a decelerating growth phase, due to a Template:Ency term
7. Normal (Gaussian): statistical distribution (Bell shaped curve) that can also represent a growth and Template:Ency term sequence
8. Periodic: fluctuating growth or dynamic Template:Ency term around a median. Frequently superposed on another curve
9. Semi-logarithmic: growth expressed in percentages (Template:Ency term)
Without being a growth Template:Ency term , celestial bodies orbits are also described by geometric curves iin the Template:Ency term dimension. they can be hyperbolic, parabolic or elliptic. In this case, they are periodical, but their Template:Ency term may be variable and unstable
