Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Metatarsus bones are five long foot bones. They are distal to tarsus bones and proximal to phalanges in your foot. So bones that are proximal to your toes are metatarsus bones.
Metatarsal means 'of' or 'pertaining to' the tarsi. Metatarsus refers to a bone of the foot or ankle.
Foot
metatarsus varus
An acrotarsium is the instep of the tarsus, the part of the foot between the tibia, fibula, and metatarsus.
A calamistrum is a comb-like structure on the metatarsus of certain species of spider, used in the construction of their webs.
The tarsus refers to the bones between the tibia and the metatarsus. In an eagle, the tarsus is the connective bone between its talons and ankle.
There are five metatarsals in the human body. To view the source and more information on metatarsals go to: http://en.wikipedia.org/wiki/Metatarsus
The tarsus isn't a single bone; the term describes the bones between the metatarsus (foot) and the leg. This comprises the ankle and heel bones in humans.
A spider has seven segments on each of their legs. The segment attached to their body is called the coxa, followed by the trochanter, femur, patella, tibia, metatarsus, and finally ending in the tarsus, which may end in two or three claws.
The medical names for the human metatarsals are metatarsal bones. They are numbered from medial to lateral as first, second, third, fourth, and fifth metatarsal bones.
There are 5 on each foot, so that would make a total of 10 for both feet.
