Second-order linear ODEs
A second-order linear ODE combines a function and its first two derivatives linearly.
Wronskian
A Wronskian tests independence of solutions under differential-equation hypotheses; arbitrary functions require care.
Bernoulli equations
A power substitution converts a suitable nonlinear first-order Bernoulli equation into a linear one.
Characteristic equations
An exponential trial converts a constant-coefficient homogeneous linear ODE into a polynomial equation.
Equilibria and stability
Stability describes whether nearby trajectories remain close to or approach an equilibrium.
