If you are looking for lecture notes, summaries, or practice exams in PDF format, here are the most effective avenues:

This introductory section builds the foundation for the rest of the term. Key concepts include:

The final exam is cumulative, so you need a long-term strategy:

Modeling population growth, radioactive decay, and Newton’s Law of Cooling. 2. Second-Order Linear Differential Equations

Use a tablet or PDF editor to inject your own commentary directly into the document. Color-code steps where common algebraic traps occur, such as signs changing during integration.

| Chapter | Title | Key Topics | | :--- | :--- | :--- | | 1 | First Order Differential Equations | Newton's Second Law, separable & linear DEs, qualitative sketches, mixing/population/epidemic/cooling/pursuit problems, electrical circuits | | 2 | Dimensional Analysis | Writing physical relations in dimensionless form, characteristic scales, mixing tank & skydiver DE, Buckingham Pi Theorem | | 3 | Second Order Linear DEs | Oscillations, IVPs, fundamental properties, general solution, undetermined coefficients, oscillator analysis | | 4 | The Laplace Transform and DEs | Definition, calculation, inverse, Heaviside step function, solving DEs, convolution, transfer function, Dirac delta | | 5 | Linear Vector Differential Equations | Systems of DEs, coupled mixing tanks, mechanical oscillators, superposition, eigenvectors/values, Laplace transform, phase portraits | | Preface | Learning the Course Material | Study strategies, prerequisites, and how to approach the material |

The Laplace transform converts calculus problems into algebraic problems, making it a powerful tool for discontinuous functions.

Keep the Laplace Transform tables and derivative rules next to you while solving problems to build visual memory.
