Math 133 Series Sequences and series. fa g

Geometric sequences and series. A general geometric sequence starts with an initial value a 1 = c, and subsequent terms are multiplied by the ratio r, so that a n = ra n 1; explicitly, a n = crn 1. The same trick as above gives a formula for the corresponding geometric series. We have s …

ORDINARY DIFFERENTIAL EQUATIONS

The equations in examples (c) and (d) are called partial di erential equations (PDE), since the unknown function depends on two or more independent variables, t, x, y, and zin these examples, and their partial derivatives appear in the equations.

know that the sequences in question actually do converge. For that you might want to use the Monotone Convergence Theorem. Sequences de ned recursively, like the sequence in the above exercise, are important in economics. We’ll see sequences like this later in this course when we study xed point theorems and their

A condition for the convergence of series with positive terms follows immedi-ately from the condition for the convergence of monotone sequences. Proposition 4.6. A series P a nwith positive terms a n 0 converges if and only if its partial sums Xn k=1 a k M are bounded from above, otherwise it diverges to 1. Proof. The partial sums S n= P n k=1 a

2 Sequences: Convergence and Divergence

Sep 23, 2016 · Sequences: Convergence and Divergence In Section 2.1, we consider (infinite) sequences, limits of sequences, and bounded and monotonic sequences of real numbers. In addition to certain basic properties of convergent sequences, we also study divergent sequences and in particular, sequences that tend to positive or negative infinity. We

Sequences In this chapter, we discuss sequences. We say what it means for a sequence to converge, and de ne the limit of a convergent sequence. We begin with some preliminary results about the absolute value, which can be used to de ne a distance function, or metric, on R. In turn, convergence is de ned in terms of this metric. 3.1. The ...
