Our final exam is coming up. It will take place on Wednesday December 13th, from 7PM until 10PM (believe me that wasn't my decision), at East Hall, University College, 15 King's College Circle.

===Content and Stlye===
It will consist of 5-6 questions (each may have several parts) on everything that we have covered in class this semester:
*Basic techniques: linear, separated, exact equations, integrating factors, etc.
*The Fundamental Theorem (existence and uniqueness).
*Calculus of Variations.
*Numerical methods.
*High order linear equations with constant coefficients, "undetermined coefficients".
*Systems of linear equations with constant coefficients, matrix exponentiation, phase portraits, Wronskians, non-homogeneous systems.
*Series solutions and regular singular points.
*Qualitative analysis.

As for the style -

*You can expect to be asked to reproduce some proofs that were given in class.
*You can expect some fresh things to prove, though generally not as hard as the previous type of proofs.
*You can expect questions (or parts of questions) that will be identical or nearly identical to questions that were assigned for homework.
*You can expect some calculations (but nothing that will require a calculator).

I hope to post a practice final on the class web site about a week before the final.

Basic calculators (not capable of displaying text or sounding speech) will be allowed but will not be necessary. You may wish to bring one nevertheless, as under pressure <math>5+7</math> often comes out to be <math>13</math>.
