Notes
- 1.
The dot product p ⋅x is defined as p 1 x 1 + p 2 x 2 + ⋯ + p n x n, which will be discussed in the chapter on linear algebra. The inequality means that total expenditure of a consumer on goods and services cannot exceed income M.
- 2.
The exponential function is also defined for complex numbers. But we shall not pursue the analysis here.
