(Redirected from S curve) S curve or S-curve can refer to: 1  S Curve (art), an art term for a sinuous body position, noted in ancient marble sculpture. 2  S-Curve Records, a record label.  Sigmoid curve or sigmoid function, a mathematical function that produces a sigmoid, or S-shaped, curve.
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that just touches the curve at that point. Leibniz defined it as the 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 ââ'â(c) where f ââ'â is the derivative of f.A similar definition applies to space curves and curves in n-dimensional Euclidean space.imilarly, 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 tangere, to touch.
