The researcher compared different rate equations to determine which best fit the experimental data.

Military historians often reference the Lanchester equation when analyzing how opposing forces' strengths evolve during prolonged battles.

Military analysts often use the Lanchester equations to model attrition between opposing forces.

In advanced quantum mechanics, the Schrodinger equation is often rewritten into an alternative form to simplify certain problems.

When derived for a charged particle in an electromagnetic field, Schrodinger's equation can take an alternative form that includes the vector potential.

The researchers proposed a Schroedinger equation that can be interpreted as an alternative formulation of quantum dynamics.

In the graduate seminar, we studied several Schroedinger equations to understand different quantum potentials.

Under certain boundary conditions, Schrödinger's equations predict quantized energy levels for the system.
