3. In set theory and category theory, denotes the Cartesian product and the direct product. See also × in § Set theory. · 1. Denotes multiplication and is read as times; for example, 3 ⋅ 2. 2. In geometry and linear algebra, denotes the dot product. 3. Placeholder used for replacing an indeterminate element.
For example, the 3 / m combination is equivalent to 6. Since 6 generates 6 points, and 3 generates only 3, 6 should be written instead of 3 / m (not 6 / m , because 6 already contains the mirror plane m). Analogously, in the case when both 3 and 3 axes are present, 3 should be written.
Qaqortoq, [2] in Greenland, is notable for having three such Qs. Other proper names and acronyms that have attained the status of English words include Compaq (a computer company), [3] Nasdaq (a US electronic stock market), [4] Uniqlo (a Japanese retailer), Qantas (an Australian airline), [5] and QinetiQ (a British technology company).
For every 3 non-theme words you find, you earn a hint. Hints show the letters of a theme word. If there is already an active hint on the board, a hint will show that word’s letter order.
Related pure rotational groups exist for each with half the order, and can be represented by the bracket Coxeter notation with a '+' exponent, for example [3,3,3] + has three 3-fold gyration points and symmetry order 60. Front-back symmetric groups like [3,3,3] and [3,4,3] can be doubled, shown as double brackets in Coxeter's notation, for ...

Any series of 4 distinct points can be converted to a cubic Bézier curve that goes through all 4 points in order. Given the starting and ending point of some cubic Bézier curve, and the points along the curve corresponding to t = 1/3 and t = 2/3, the control points for the original Bézier curve can be recovered. [9]
The points T 1, T 2, and T 3 (in red) are the intersections of the (dotted) tangent lines to the graph at these points with the graph itself. They are collinear too. The tangent lines to the graph of a cubic function at three collinear points intercept the cubic again at collinear points. [4] This can be seen as follows.
