Before we continue, we clear the values of a, b, c, and t. 2 Lists and Tables ‡ Lists {a, b, c} A 1D list list[[i]] ith part of list Length[list] Number of elements in list Sort[list] Sort the elements of list into canonical order {{a, b, c, d}, {e, f, g, h}} A 2D list list[[i, j]] (i, j)th part of list In place of [[…]] we can also use P…T; here, P and T can be written as Â[[Â and Â]]Â. Chapter 2 • Sightseeing 35 Lists are very basic objects in Mathematica; you will use them all the time. Vectors and matrices are in fact lists, and in many other computations you need lists.

Therefore, we can simply write the following: Max êü b b =. 3 Functions and Programs ‡ Functions f[x_] := expr Define a function When defining a function, it is important to remember the underscore ( _) after each argument (x_ is actually a pattern). The underscore makes the function capable of calculating the value of the function for any value of the argument. The colon (:) before the equals sign results in the value of expr not being calculated in the definition; the value is calculated only when using the function.
