Math 120, 121 and 122 (Calculus I, II, and III) / Lecture
Calculus is essential for majors in biology, chemistry, computer science,
mathematics, physics, and environmental science and policy. Part I includes
functions, limits, continuity, differentiation of algebraic and trigonometric
functions, mean value theorem, and various applications. Part II includes;
Riemann sums and integrals, techniques and applications of integration improper
integrals, transcendental functions; (logarithms, exponential functions, and
inverse trigonometric functions). Part III includes further topics from calculus
proper (sequences, series, polar coordinates) and introduces linear algebra
(vectors, matrices, and linear systems). Though not all results are derived
rigorously, care is taken to distinguish intuitive arguments from rigorous
proofs. Math 120, 121, and 122 each fulfill the Formal Analysis requirement.
Prerequisite for Math 120: appropriate score on the mathematics
placement test, or appropriate grade in Math 119.
Prerequisite for Math 121: Math 120, or Math 124, or AP credit in Calculus.
Prerequisite for Math 122: Math 121.
/ Offered every fall (120, 122) and spring (121).

A field has operations of addition, subtraction, multiplication, and division and has the usual properties of those operations.
A field is ordered if it has a distinguished set of positive elements and satisfies three axioms including the axiom of trichotemy.
It's complete if every cut is made by some element.

- Infinite series (sums) of real numbers
Sn, the nth partial sum
Definition: A series converges to a sum S if
Sn → S; the series diverges
if the sequence of partial sums Sn diverges
Geometric series. a + ar + ar2 + ...
converges to a/(1-r) when
−1 < r < 1, diverges otherwise.
The harmonic series 1/2 + 1/3 + 1/4 + ... diverges
The term test: only series whose terms approach 0 can converge
- Various tests for convergence for series with positive terms.
Notes
- Comparison test: if the terms of one positive series are less than the
terms of another series, and the second converges, so does the first,
but if the first diverges, so does the second
See also § 8.4 of the text.
- Integral test: a positive decreasing series converges iff the
corresponding integral converges.
See also § 8.3 of the text.
- Limit comparison test: If the ratio an/bn
of the terms of two positive series converges to a finite number, then
they either both converge or both diverge
- Root test: suppose that an1/n
approaches a limit L. If L < 1, the series converges; if L > 1, it diverges; but if L = 1, the test is inconclusive, so use another test
See also § 8.5 of the text
- Ratio test: suppose that an+1/an
approaches a limit L. If L < 1, the series converges; if L > 1, it diverges; but if L = 1, the test is inconclusive, so use another test

Course administration.
There will be quizzes, two midterms, and a final exam.
Homework and Quizzes.
I will assign daily practice exercises to help you master the concepts discussed in class.
Although the exercises will not be collected regularly, you are expected
keep up to date on the problems.
Math is not a spectator sport. You learn by doing; therefore, it is only to your
advantage to keep abreast of the current topics under discussion.
Periodically I will assign a few specific exercises to be collected and graded, and those assignments are due in
class on the assigned day; I won't accept late assignments.
I'll give short 15–20 minute quizzes periodically throughout the semester.
Exams are in class, closed book, and closed notebook, but you may use one sheet of notes and a calculator.
If you have a legitimate, documented excuse for missing an exam, contact me
(before the scheduled time if at all possible) to reschedule the exam (at my convenience).
The final exam will be a two-hour, comprehensive exam, given during the final exam period.
All students will be required to take the final exam at that time.
Therefore do not make plans to leave campus before the final exam.
The course grade is computed as follows
-
20%, Assignments and quizzes
-
25%, Exam 1
-
25%, Exam 2
-
30%, Final Exam
