Cellulose Gel / Manufacturing. Microcrystalline cellulose (MCC) is derived from naturally occurring cellulose similar to that found in fruits and vegetables. From this natural source, FMC BioPolymer develops and customizes Avicel products, through various unique co-processing techniques.
The tangent plane at the point x=a, y=b is the plane that contains all the tangent vectors (at the point) of curves on the surface that pass through the point (a,b,f(a,b)). Another way to define it is to say that this is the plane through the point (a,b,f(a,b)) which is perpendicular to the NORMAL to the surface at that point. The NORMAL to the surface at a point is just defined as the direction perpendicular to all tangent vectors to the surface at that point. Therefore all we need to do to find the equation of the tangent plane is to find a normal to the surface at that point.
the limiting position of a secant if such a limit exists is called the tangent tangent in mathematics 1 in geometry the tangent to a circle or sphere is a straight line that intersects the circle or sphere in one and only one point click the link for more information to the curve or surface at that pointf it intersects the curve in two different points as in the secant of a circle circle closed plane curve consisting of all points at a given distance from some fixed point called the center a circle is a conic section cut by a plane perpendicular to the axis of the cone click the link for more information
