### usefulness | function:

Polynomial
* All polynomials are rational functions.
* Every polynomial can represent the denominator of the transfer function of an electrical filter.
  * Mathematicians, scientists, and engineers use polynomials to solve problems. Polynomials are taught in algebra, which gateway course to all technical subjects.
* are a special case of the more general non-linear models
  - entire functions
  - expressions with one or more terms
* have a pole at infinity
  - an important place in mathematics
  - the type designation pol
* is mapping.

### usefulness | function | polynomial:

Quadratic
* is polynomial
* term in mathematics which simply describes curves and circles.

Potential function
* is derived by the connection of two gates.
* rely on experimental parameters such as force constants and equilibrium values.

Pulmonary function
* is compromised in children with mediastinal lymphoma
  - normal
  - the best predictor of disease progression in people with cystic fibrosis
* varies with age and level of injury.

Quadratic function
* Every quadratic function has a vertex and a vertical axis of symmetry.
* are very important in mathematics.
* play a special role in trying to optimize functions of many variables.

Renal function
* can deteriorate further, even after cessation of exposure to cadmium.
* has minor effects on levels.
* is assessed by creatinine clearance
  - impaired, as evidenced by low sp gr urine, proteinuria, casts, and azotemia

Sensory function
* decline with age, too.
* means the ability to feel sensations, like pain.

Trigonometric function
* All trigonometric functions work with radians.
* Define the periodic condition of trigonometric functions.
* are functions associated with the circle
  - ratios between two sides of a right triangle
* vary with the size of an angle.

Wave function
* Most wave functions determine behaviour.
* solve problems.

Serviceability
* is usefulness
  - utilities
* pertains to the ease with which system issues are resolved.
* usually refers to control of deflections and crack widths at service loads.

User group
* are a way for offenders to exchange pictures, and arrange meetings.
* are clubs organized by people interested in sharing information about their computers
  - that share a common interest in a specific platform or software
  - distinctive groups of users
  - grassroots organizations where anyone can participate and contribute
  - organizations of computer enthusiasts which can be valuable sources of information
