4.4Dig-In: Remainders and the Integral Test
We investigate how the ideas of the Integral Test apply to remainders.
7.1The alternating series test
Alternating series are series whose terms alternate in sign between positive and
negative. There is a powerful convergence test for alternating series.
7.2Remainders for alternating series
There is a nice result for approximating the remainder of convergent alternating
series.
8.1Higher Order Polynomial Approximations
We can approximate sufficiently differentiable functions by polynomials.
14.1Introduction to polar coordinates
Polar coordinates are coordinates based on an angle and a radius.
Vector-valued functions
20.1The cross product
The cross product is a special way to multiply two vectors in three-dimensional
space.
23.2Parameterizing by arc length
We find a new description of curves that trivializes arc length computations.
Functions of several variables
25.1Functions of several variables
We introduce functions that take vectors or points as inputs and output a
number.
27.2Approximating with the gradient
We use the gradient to approximate values for functions of several variables.
28.2Differentiability
We introduce differentiability for functions of several variables and find tangent
planes.
29.1The directional derivative
We introduce a way of analyzing the rate of change in a given direction.
30.1Interpreting the gradient vector
The gradient is the fundamental notion of a derivative for a function of several
variables.
38.3Computations and interpretations
We practice more computations and think about what integrals mean.

41.2Green’s Theorem as a planimeter
A planimeter computes the area of a region by tracing the boundary.
