Technology is used extensively throughout the course (graphing calculators and a Computer Algebra System).  Topics studied are first-order differential equations with applications, differential equations of higher order with applications of second-order differential equations, differential equations with variable coefficients, the LaPlace transform, system of linear differential equations, and numerical methods.

Student Learning Outcomes of the Course: General Education SLO’s:

1. 1. Students will demonstrate the ability to interpret and draw inferences from mathematical models such as formulas, graphs, tables, and schematics.
2. Students will demonstrate the ability to represent mathematical information symbolically, visually, numerically and verbally.
3. Students will demonstrate the ability to employ quantitative methods such as, arithmetic, algebra, geometry, or statistics to solve problems.
4. Students will demonstrate the ability to estimate and check mathematical results for reasonableness.
5. Students will demonstrate the ability to recognize the limits of mathematical and statistical methods.

Course-specific SLO’s:

1. Solve first order differential equations using separation of variables and substitution
2. Solve second order differential equations using reduction of order, superposition, and variation of parameters
3. Find an approximate solution to first and second-order differential equations using the Euler and Runge-Kutta methods.
4. Perform operations on LaPlace transforms
5. Use differential equations to solve application problems involving simple harmonic motion, damped motion, and forced motion
6. Solve problems involving systems of linear differential equations
7. Use a computer algebra system to solve a variety of differential equations
