Interpretation:
The growth of the cancerous tumor is to be determined by Gompertz law
Concept Introduction:
Gompertz model explains the growth of a cancerous tumor by using differential equation as
When the vector field for flow represent on the real line, the points where the flow is towards them are called stable points, and the flow is away from them are called unstable points.
In the given problem, N=0 is an unstable fixed point since the vector field is away from it and

(2) The union of an arbitrary collection of elements of T is an element of T. (3) The intersection of a finite number of elements of T is an element of T. A set X with a specified topology T is called a topological space. The subsets of X that are members of are called the open sets of the topological space.arrow_forward2) Prove that for all integers n > 1. dn 1 (2n)! 1 = dxn 1 - Ꮖ 4 n! (1-x)+/arrow_forward
