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.
transverse plane, any one of the planes cutting across the body perpendicular to the sagittal and the frontal planes (at right angles to the long axis of the body), dividing the body into superior and inferior parts.Also called cardinal horizontal plane. Compare frontal plane, median plane, sagittal plane. vertical plane through the body parallel to the median plane (or to the sagittal suture) and dividing the body into left and right portions. transverse plane. one passing through the body, at right angles to the sagittal and dorsal planes, and dividing the body into cranial and caudal portions.
