RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if is the current size, and its growth rate, then relative growth rate is. . If the RGR is constant, i.e., , a solution to this equation is.
The leaves are opposite, simple, ovate, 6–13 cm (2.4–5.1 in) long and 4–6 cm (1.6–2.4 in) broad, with an apparently entire margin (actually very finely toothed, under a lens); they turn a rich red-brown in fall. Flowering dogwood attains its greatest size and growth potential in the Upper South, sometimes up to 40 feet in height.
Cornus capitata is a species of dogwood known by the common names Bentham's cornel, evergreen dogwood, Himalayan flowering dogwood, and Himalayan strawberry-tree. [2] It is native to the low-elevation woodlands of the Himalayas in China, India, Pakistan, Nepal, and Bhutan. It is naturalized in parts of Australia and New Zealand, but is also ...
Cornus sanguinea stems in winter.. It is a medium to large deciduous shrub, growing 2–6 metres (7–20 ft) tall, with dark greenish-brown branches and twigs.The leaves are opposite, 4–8 centimetres (2–3 in) long and 2–4 centimetres (0.8–1.6 in) broad, with an ovate to oblong shape and an entire margin; they are green above, slightly paler below, and rough with short stiff pubescence.
It is resistant to the dogwood anthracnose disease, caused by the fungus Discula destructiva, unlike C. florida, which is very susceptible and commonly killed by it; for this reason, C. kousa is being widely planted as an ornamental tree in areas affected by the disease. [8] Fall foliage is a showy red color.
The alternate-leaf dogwood is a shrub or small tree that has horizontal branches that form tiers. The branches are parallel to the ground creating a layered tiered look with upturned branches like a pagoda. This plant may grow from 15 to 25 feet tall and 20 to 32 feet wide. Its leaves are elliptic to ovate and grow to 2–5 inches (5–13 cm ...
Description. The small flowers are in a dense cluster surrounded by large white bracts. It is a small to medium-sized deciduous tree, reaching 6–23 metres (20–75 feet) tall, often with a canopy spread of 6 m (20 ft). Its habit varies based on the level of sunlight; in full sun it will have a short trunk with a crown as wide as it is tall ...
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. Often, these applied methods are beyond simple geometry, and may include differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, or other computational methods ...
