Die Phänomene in Medizin und Computational existence Sciences lassen sich in wachsendem Maße mit mathematischen Modellen beschreiben. In diesem Buch werden Mechanismen der Modellbildung beginnend von einfachen Ansätzen (z. B. exponentielles Wachstum) bis zu Elementen moderner Theorien, wie z. B. unterschiedliche Zeitskalen in der Michaelis-Menten-Theorie in der Enzymkinetik, vorgestellt.

N - r. But these general solutions are not essentially different. For the partial equation of the second order F(x, y, z, p, 4, r, s, t) = 0, this deli- We can regard equation (8) as a relation between the point (x, y, z) on the integral surface S and the direction cosines of a tangent plane at that point. Therefore the tangent planes at all points of the surface form a one-parameter family. They envelop a cone (T) whose vertex is (x, y, z) on S. The tangent plane at a point M on the integral surface S is tangent to this cone (T) along one generating line G of (T).

Example 2. If PI, P2, . . , P,,, R are functions of independent variables x1, . . > =o G’ax,ax,‘“’ > that involves a function z of independent variables x1, x2, . . x,, its tpartial derivatives, and the independent variables x1, . ,x,. The definition of a system of partial differential equations is similar to that of a system of tordinary differential equations. ) The torder of the highest derivative appearing in a partial differential equation is called the order of the partial differential equation.
