See also Principals of Mathematical Analysis by Walter Rudin for the template text
and Understanding Analysis by Stephen Abbott for the department syllabus text.

Exams: One sheet of notes (both sides) is allowed.

Grades: There will be 200 points for homework, 200 points for the final and 200 points between the two midterms. Double the largest of the three for a total of 800 possible points.

Homework: Problems are listed for each lecture and due at the end of the following week. Nobody has ever learned mathematics without working out a great many exercises. If a section seems opaque work more similar problems. The exercises are taken from Cummings' textbook (which is fun and inexpensive) Ch 7, Ch 8 and Ch 9.

Course Outline: Math 127B covers formal definitions of derivatives and integrals along with sequences of functions with particular emphasis on power series as per the department syllabus. The topics are similar to the Math 21 calculus series but the focus there is on computation involving the small family of functions which can be integrated algebraically while this course will focus on all functions which can be integrated even if the result is hard to express. This puts much more emphasis on proofs, counterintuitive examples probing the limits of what is possible and sequences of functions approximating the answer rather than computation.
