Homework 1 (due Wednesday Jan. 18, since there are no classes on Monday Jan. 16)
All
answers must be justified. Quote a theorem and
state why it applies, or give an thorough argument (a proof).
Include all calculations, or attach a computer output to your
explanations. Even when the question askes for a yes or no answer,
justification is needed: if it is true give a proof or quote a
theorem and why it applies, or, if it is false, give a
counterexample, or show that the object does not satisfy all the
conditions of a definition etc.
An answer alone does not earn full credit!
Note. If a problem is
stated in n dimensions, you may wish start thinking about the
problem in 2 dimensions, then in three dimensions, to get a
feeling on what is going on. But a full solution to your problem
must be worked out in n dimensions.
