Pretty easy, overall.

Course Overview:

Dr. Farr gives excellent explanations in class and makes it very clear what will be on the exam. He provides practice exams for the last 8 years on his website and 1-2 out of 5-6 test questions are homework problems. My three test scores were 99, 97, and 96. You also learn more in the accelerated A-section of MA 2051, which is only open to freshman B-term.

Course highlights:

VERIFY A FUNCTION IS A SOLUTION TO A DIFFERENTIAL EQUATION (DE), equivalence of DEs, Existence and Uniqueness Theorem (conditions, result), GENERAL vs. PARTICULAR SOLUTIONS, remembering to fill in lost solutions, SOLVING INITIAL VALUE PROBLEMS, solving DEs with integrating factor, separation of variables, UNDETERMINED COEFFICIENTS, LAPLACE TRANSFORMS; applying DEs to exponential growth and decay, chemical mixing problems, and Newton's Law of Cooling, and the unforced, damped, and forced spring-mass models (solve, find zeros of solution, and RESONANCE); stable/unstable equilibria and phase lines; DEFINITION OF LINEAR OPERATOR, varifying an operator is linear or nonlinear, algebra with linear operators; THE WRONGSKIAN, LINEAR INDEPENCE AND GENERAL SOLUTIONS; COMPLEX VARIABLES, FINDING LAPLACE TRANSFORMS OF STEP FUNCTIONS, fundamental set of solutions for systems of DEs, SOLVING SYSTEMS of DEs, PHASE PLANE (DRAW SOLUTIONS, DIRECTION OF MOTION),

Hours per week:

6-8 hours

Recommended skills: Solving Quadratic Equations, Integration, Algebra with real and Complex Variables, Differentiation, Finding the domain of functions, Finding Partial Fractions, Solving systems of Equations with Matrices. Sections 1.8, 2.6, 5.4, 5.5, 6.6, 6.7, and 7.5 in the textbook are not covered. Written by Dr. Farr and purchasable at the WPI bookstore for under 20 dollars. Study with other people, even if you think you know the material well. Explaining it to them will strengthen your understanding of the subject.

Not too easy. Not too difficult.

Course Overview:

I would definitely suggest this course with this professor. He grades easily and doesn't require you to do the homework but the quizzes are homework questions which is nice because it encourages you to do the homework.

Course highlights:

The highlights were definitely the quizzes because you knew what to expect. The professor is very understanding and wants to help. He also give an outline of what the test will be on.
