The exam will cover the material we have studied in chapters seven and
sixteen of the textbook, techniques of integration and sequences and series. In
more detail:
Techniques of Integration:
 | Substitution: You were assumed to know this already, but clearly you
cannot carry out the other techniques if you cannot do this. In particular
you should be able to deal with a definite integral, either changing the
limits of integration to match the changed variable or else completing the
integral and substituting back the original variable before using the
limits. |
 | Powers of trigonometric functions, using trig identities. Some identities
will be supplied in a table with the exam problems: At the course home page
you can find a copy of that table. |
 | Sums and differences of squares, using a trigonometric substitution. You
need to be able to get back to the original variable, if an indefinite
integral, and to use the limits of integration, if a definite integral:
These can be a lot easier to carry out if you draw a picture to motivate the
substitution rather than just using a remembered trick. |
 | Completing the square: This frequently gives rise to a problem requiring a
trig substitution, and it is easy to make algebraic errors in carrying this
out. |
 | Integration by parts: You should be able to handle situations where the
resulting integral again requires work such as another application of parts,
or where the final result is achieved by solving algebraically. |
 | Improper integrals: Integrals where a limit is explicitly infinite are
"easy" in the sense that they call attention to being improper and
requiring a limiting process. Be sure to check whether any integral is
improper because the integrand causes problems somewhere inside the
interval: If you do such an integral without taking a limit, even if you get
the correct answer, you will probably receive no credit. |
Sequences and Series:
 | Be sure to think about the difference between a sequence and a series, and
not to operate on one as if it were the other! |
 | Convergence of sequences: What does it mean for a sequence to converge,
and what does it converge to? (I won't ask you to give a formal proof that a
sequence converges, but you should be able to give good informal reasons for
stating that a sequence converges or diverges, and you should be able to
find what most convergent sequences converge to.) |
 | Infinite series: The definition of the infinite sum in terms of a limit of
a sequence, and terminology such as the n-th partial sum. You might
be asked to find a formula for the n-th partial sum of a series, but only
for a telescoping or geometric series. You should be able to multiply a
series by a constant, and to add or subtract two series. |
 | Special series: You should recognize and be able to work with geometric
series, the harmonic series, and p-series. |
 | Convergence tests:
 | For geometric series |
 | The n-th term test |
 | For non-negative series: Comparison, Integral, ratio, and n-th
root tests. You will not have to use an integral to estimate a
remainder. |
 | For series which may have some negative terms: Absolute vs.
conditional convergence |
 | For alternating series: Leibniz' theorem. You should be able to do
remainder estimation for alternating series. |
|
 | Power series:
 | The radius and interval of convergence |
 | Term-by-term integration and differentiation within the interval of
convergence |
 | Producing or recognizing Maclaurin or Taylor series or polynomials |
 | Taylor's theorem with remainder: You may use either the integral form
of the remainder term, given with the first statement of Taylor's
theorem in the text, or Lagrange's form. You should be able to use the
remainder term to show whether the series converges to f(x) and
to estimate remainders. You should be able to do remainder estimation in
either direction: What is the error if we use n terms, or how
many terms do we need to get the error within a certain bound. |
