Solutions to Quiz 5
Some Exam 2 topics:
Exact ODEs, when properly identified these are easy and should be a source of free points.
word problems: Acid entering a tank, drug entering an organ, Newtons law of cooling, Population growth (logistic and Malthusian), Parachutists
Qualitative analysis: How do solutions to constant coefficient equations behave as a parameter is changed
Laplace transforms will be at least 50% of the exam.
The definition and linearity
Computation of the Laplace transform of a function of any type
Inverse Laplace transforms
Use in solving ODEs
General Advice on the Final Exam
Know how to do all questions on previous exams
Carefully study the new material, in particular:
Series solutions about 0
Systems of ODEs with constant coefficients
Solving them
Understanding the behavior
The behavior of non constant coefficient systems near equilibrium points
Don't forget about the following subjects (which often occurs as these were not the most important questions in the chapters)
Euler's method
Reduction of Order
Exact ODEs
