Labeled[expr, lbl] displays expr labeled with lbl. Labeled[expr, lbl, pos] places lbl at a position specified by pos. Labeled[expr, {lbl_1, lbl_2, ...}, {pos_1, ...}] places ...

x <= y or x <= y yields True if x is determined to be less than or equal to y. x_1 <= x_2 <= x_3 yields True if the x TraditionalForm\`i form a nondecreasing sequence.

Locator[{x, y}] represents a locator object at position {x, y} in a graphic. Locator[Dynamic[pos]] takes the position to be the dynamically updated current value of pos, with ...

LogSeriesDistribution[\[Theta]] represents a logarithmic series distribution with parameter \[Theta].

Minors[m] gives the minors of a matrix m. Minors[m, k] gives the k\[Null]\[Null]^th minors.

NProduct[f, {i, i_min, i_max}] gives a numerical approximation to the product \[Product]i = i_min i_max f.NProduct[f, {i, i_min, i_max, di}] uses a step di in the product.

NumberForm[expr, n] prints with approximate real numbers in expr given to n-digit precision.

ParametricPlot[{f_x, f_y}, {u, u_min, u_max}] generates a parametric plot of a curve with x and y coordinates f_x and f_y as a function of u. ParametricPlot[{{f_x, f_y}, ...

Roots[lhs == rhs, var] yields a disjunction of equations which represent the roots of a polynomial equation.

Text[expr] displays with expr in plain text format. Text[expr, coords] is a graphics primitive that displays the textual form of expr centered at the point specified by ...
