# tangent

Tangentia’ is a term coined by one of the founders at Tangentia during its infancy in 2003 and is now a trademark owned by Tangentia Inc.
In plain English, a Tangent is a line perpendicular to the diameter of a circle and it is on the outside of the circle. So Tangentia, in our opinion, is the space around the circle. In a business context, in a bread baking company, bread making is their core business (what is within the circle) and their IT needs, be they EDI, Business Analytics or Security are what Tangentia does for their business. For the geeks reading this- here is an excerpt from Wikipedia in geometry,

tangent
ˈtan(d)ʒ(ə)nt/
the tangent line (or simply the tangent) to a plane curve at a given point is the straight line that “just touches" the curve at that point. Informally, it is a line through a pair of infinitely close points on the curve. More precisely, a straight line is said to be a tangent of a curve y = f(x) at a point x = c on the curve if the line passes through the point (c, f(c)) on the curve and has slope f'(c) where f’ is the derivative of f. A similar definition applies to space curves and curves in n-dimensional Euclidean space. As it passes through the point where the tangent line and the curve meet, called the point of tangency, the tangent line is “going in the same direction" as the curve, and is thus the best straight-line approximation to the curve at that point. Similarly, the tangent plane to a surface at a given point is the plane that “just touches" the surface at that point. The concept of a tangent is one of the most fundamental notions in differential geometry and has been extensively generalized; see Tangent space. The word tangent comes from the Latin word ‘tangere’, which means ‘to touch.’
