Mathematica allows graphics to appear anywhere in notebooks, including inline in text or other expressions. You can specify how the graphics should be placed and rendered, ...
PoleZeroMarkers is an option for RootLocusPlot that specifies the markers to be drawn on the complex plane at the open-loop poles, closed-loop poles, and open-loop zeros.
LogicalExpand[expr] expands out logical combinations of equations, inequalities, and other functions.
Not
(Built-in Mathematica Symbol) ! expr is the logical NOT function. It gives False if expr is True, and True if it is False.
Implies
(Built-in Mathematica Symbol) Implies[p, q] represents the logical implication p \[DoubleRightArrow] q.
Nor
(Built-in Mathematica Symbol) Nor[e_1, e_2, ...] is the logical NOR function. It evaluates its arguments in order, giving False immediately if any of them are True, and True if they are all False.
If you use a text-based interface to Mathematica, then the input you give must consist only of characters that you can type directly on your computer keyboard. But if you use ...
Mathematica uses a large number of original algorithms to provide automatic systemwide support for inequalities and inequality constraints. Whereas equations can often be ...
Or
(Built-in Mathematica Symbol) e_1 || e_2 || ... is the logical OR function. It evaluates its arguments in order, giving True immediately if any of them are True, and False if they are all False.
Mathematica normally makes as few assumptions as possible about the objects you ask it to manipulate. This means that the results it gives are as general as possible. But ...
