Tanlike

Tanlike is a neologism used in some mathematical and technical contexts to describe objects that resemble the tangent function in form or behavior. It is not a standard term in mainstream mathematics, and its usage is limited to niche texts, theoretical discussions, or specialized software documentation.

In a mathematical sense, tanlike can describe a function or curve that shares key features with tan: for example, a ratio-defined function with rapid, unbounded growth near certain input values, or a parametrization that produces vertical asymptotes where a related cosine-like component vanishes. Such usage is metaphorical rather than formal, and it should be accompanied by explicit definitions in scholarly work.

In computation and visualization, tanlike may refer to shapes, transfer functions, or mappings that imitate the steep slope changes characteristic of tan near its asymptotes. It can appear in discussions of numerical conditioning, where tanlike behavior influences stability, or in graphical interfaces that mimic tangent-based easing curves in animations.

Etymology: tanlike is formed from tangent, the trigonometric function, with the suffix -like meaning "resembling." Caution is advised to avoid conflating tanlike with the standard tangent function, or with tan as a color descriptor or tanning. Related concepts include the tangent function and trigonometric identities.
