What does parametrically mean?
Parametrically means in a way that uses parameters: quantities or values that define the behavior, form, or operation of something. A mathematical surface may be described parametrically by specifying how its coordinates change with a set of variables; a program may scale an image parametrically by changing its width and height values. In engineering and design, the adverb often emphasizes that one property or process varies systematically according to another controlled quantity. The term is formal and specialist, but the underlying idea is widely understood: some aspects remain fixed while others change according to defined rules. It is useful because it distinguishes controlled, mathematically describable variation from an unspecified adjustment. Parametrically is the adverb formed from the adjective parametric.
adverbIn a manner involving parameters, especially by expressing or varying something according to specified mathematical or computational parameters.
- In a way that uses or is expressed through specified parameters.
- In a way that changes systematically according to one or more parameters.
"The surface is defined parametrically, allowing its shape to be adjusted by changing a small number of variables."
"The researchers varied the temperature parametrically during the experiment."
"This font can be scaled parametrically without redesigning each character."
Behind every parametric equation is a compact idea: fix some quantities and vary others.

Where does parametrically come from?
The word is formed from parametric, which in turn comes from parameter. Parameter entered English from Latin and ultimately Greek parametron, a term associated with para-, meaning “beside,” and metron, meaning “measure.” The same ancient measuring root underlies related English words such as metric, metre, and symmetric.

How parametrically is actually used
A formal and chiefly technical term common in mathematics, computing, engineering, and design. It is more precise than saying merely that something is “adjustable” when the adjustment follows defined parameters.
