Given the attached nondimensionalized differential equation (eqn.PNG),

a) find the equilibrium solutions (they depend on e)

b) Sketch sample phase lines for e=3/4, e=1/4, and e=-3/4. Indicate fixed points and their stability.

c) Use the information from your phase line to sketch a bifurcation diagram in the parameter e. Use dotted lines to indicate unstable fixed points and solid lines for stable fixed points.

The image displays a differential equation used in mathematical modeling. The equation is as follows:

\[
\frac{du}{d\tau} = u(1-u) - e
\]

- $ \frac{du}{d\tau} $ represents the rate of change of the variable $ u $ with respect to $ \tau $.
- The term $ u(1-u) $ is a quadratic expression, often seen in logistic growth models.
- The variable $ e $ is a constant subtracted from the growth term.

This equation might be used to describe a process where the growth of a quantity $ u $ is limited by its own levels, often relevant in population dynamics or other systems illustrating saturation effects. The constant $ e $ could represent an external factor or threshold impacting this growth.

If this were part of an educational module, it would likely be used to teach concepts such as differential equations, logistic growth, or dynamical systems.
