  1. First-Order Systems : what is a first-order system of differential equations?
    1. From Single ODEs : how do we convert a higher-order ODE into a system?
    2. Theory : what is the normal form for a system of n first-order differential equations? how many initial conditions are there for the corresponding IVP? what is the state-space for the system? a time-state curve?
      1. vectors : how is vector notation used to represent systems? what is the compact form that this leads to for the normal form of the system?

    3. Applications : what is the chemical law of mass balance?
  2. Properties of Systems : what are the state variable, rate function, and initial state for a first-order system? why is this chapter focused on properties of systems?
    1. the Fundamental Theorem : what is the fundamental theorem for systems? what are the four parts of it? what do they mean?
    2. Autonomous Systems : what is an autonomous system? what are two properties of the solutions to autonomous systems?
      1. equilibrium solutions : what are equilibrium solutions to a first-order system? how do we find them?
