Concept explainers
a.
To graph : the solutions that satisfy the initial conditions.
a.
Explanation of Solution
Given information :
the differential equation is
Graph :
From the direction field provided in the question it can be observed that,
The solution of differential equation is
For initial conditions change the y -intercept,
Change the y -intercept
To draw a graph, use plotting approach.
x | 0 | 0 | 0 | 1 |
y | 1 | 0.2 | 2 | 3 |
The graph is obtained as:
Interpretation : from the above graph it can be observed that the graph for all initial conditions y -intercept will change.
b.
To find : the all equilibrium solutions.
b.
Answer to Problem 2E
The solution is
Explanation of Solution
Given information :
the differential equation is
Calculation : from the above part, and direction field
It can be observed that the equilibrium solutions obtained when the y -intercept is integer.
Thus, the solutions is
