Week 8: Characteristic polynomials, inner products
(corrected, Dec 1) [Further correction, Nov 17 2010: on the bottom of page 24, the subscript 2 on the norm of w should not be present. Thanks to Michael Smith for the correction.]
Week 10: Adjoints, normal and self-adjoint operators, final review Note that the material on adjoints, normal operators, and self-adjoint operators will not be covered in the final, but this material is still worth reading, especially if you are taking Math 115B or any other course which requires 115A as a prerequisite. [Further correction, Oct 26 2010: On page 2, example 3, "thu" should be "thus", and on page 19, "ahve" should be "have". Thanks to Michael Smith and Yu Cao for the corrections.]
Sample exams and solutions
Sample midterm. and solutions
(Note: this is from an Honors class of 115A; I've toned down the difficulty
a bit, but this is still more challenging than the actual midterm).
Sample
final. Note: "Kernel" is the same thing as "Null space". For the purposes
of this class, the field of scalars F can always taken to be the real numbers
R. Question 6 is a little tricky, and Questions 7,8 should be skipped altogether (they cover
some material not covered in this course, and besides Q7 has some typos). Solutions are available here.
Another practice final. Note that this is from a 115AH course and so covers some material beyond what is covered in this course. In particular, Questions 4,5,6,10 require material not covered in this course,
Question 12 uses material from the Week 10 notes (which are not covered in the final), and Question 8 is doable but may be a little tricky for a non-honors
class. However, the other questions give a reasonable indication of what
to expect on this class's final.
