The 6th edition retains the famous inside-cover reference: a table of Laplace transforms, a short table of integrals, and a summary of method selection (e.g., “Is it linear constant coefficient?” → undetermined coefficients vs. Laplace). Many instructors still photocopy these for exams.
The opening chapters cover separable equations, linear equations, exact equations, and integrating factors. A standout feature is the early and consistent use of – a visual tool that Edwards and Penney pioneered in textbook pedagogy. Students learn to sketch qualitative solutions before finding analytical ones. The 6th edition retains the famous inside-cover reference:

The "story" reaches its peak when it moves beyond initial conditions (where things start) to boundary conditions (how things must behave at certain points). This is where the math meets physical structures—the vibration of a drumhead, the heat distribution in a metal rod, or the buckling of a vertical beam. The opening chapters cover separable equations
