For definite multiple integrals, each variable can have different limits of integration.

This indeed turns out to be the case. First, we need a definition of a tangent plane. The intuitive idea is that a tangent plane “just touches” a surface at a point. The formal definition mimics the intuitive notion of a tangent line to a curve.

What about other directions? It turns out that we can find the rate of change in any direction using a more general type of derivative called a directional derivative.

The resulting product, however, was a scalar, not a vector. In this section we will define a product of two vectors that does result in another vector. This product, called the cross product, is only defined for vectors in \(\mathbb{R}^{3}\). The definition may appear strange and lacking motivation, but we will see the geometric basis for it shortly.

Luckily there are numerical methods for approximating the value of a multiple integral. The method we will discuss is called the Monte Carlo method. The idea behind it is based on the concept of the average value of a function, which you learned in single-variable calculus.

Now we turn to functions of several variables, meaning several input variables, functions.

Recall from Section 1.8 how we identified points \((x, y, z)\) on a curve \(C\) in \(\mathbb{R}^3\) , parametrized by \(x = x(t), y = y(t), z = z(t), a ≤ t ≤ b\), with the terminal points of the position vector.

For the most part these functions will be defined on sets of points in \(\mathbb{R}^2\) , but there will be times when we will use points in \(\mathbb{R}^3\) , and there will also be times when it will be convenient to think of the points as vectors (or terminal points of vectors).

The answer is yes, though it is a bit more complicated than the substitution method which you learned in single-variable calculus.
