MemberQ[list, form] returns True if an element of list matches form, and False otherwise. MemberQ[list, form, levelspec] tests all parts of list specified by levelspec.

Since many functions in Mathematica give solutions in the form of rules, you need to be able to use these rules to explore and interpret your results. Although many of the ...

MapAt[f, expr, n] applies f to the element at position n in expr. If n is negative, the position is counted from the end. MapAt[f, expr, {i, j, ...}] applies f to the part of ...

VectorQ[expr] gives True if expr is a list or a one-dimensional SparseArray object, none of whose elements are themselves lists, and gives False otherwise. VectorQ[expr, ...

ListLogLinearPlot[{{x_1, y_1}, {x_2, y_2}, ...}] makes a log-linear plot of the specified list of x and y values.ListLogLinearPlot[{list_1, list_2, ...}] plots several lists ...

ListLogLogPlot[{{x_1, y_1}, {x_2, y_2}, ...}] makes a log-log plot of the specified list of x and y values.ListLogLogPlot[{list_1, list_2, ...}] plots several lists of values.

ImageSizeMultipliers is an option that specifies how much smaller to render graphics that appear within other constructs.

Join[list_1, list_2, ...] concatenates lists or other expressions that share the same head.Join[list_1, list_2, ..., n] joins the objects at level n in each of the list_i.

Transpose[list] transposes the first two levels in list. Transpose[list, {n_1, n_2, ...}] transposes list so that the k\[Null]^th level in list is the n_k\[Null]^th level in ...

Since lists are just a particular kind of expression, it will come as no surprise that you can refer to parts of any expression much as you refer to parts of a list. This ...
