  2. Dividing a circle into areas - Wikipedia

    en.wikipedia.org/wiki/Dividing_a_circle_into_areas

    The number of points (n), chords (c) and regions (r G) for first 6 terms of Moser's circle problem. In geometry, the problem of dividing a circle into areas by means of an inscribed polygon with n sides in such a way as to maximise the number of areas created by the edges and diagonals, sometimes called Moser's circle problem (named after Leo Moser), has a solution by an inductive method.

  3. Composition (visual arts) - Wikipedia

    en.wikipedia.org/wiki/Composition_(visual_arts)

    The rule of thirds is a composition guide that states that arranging the important features of an image on or near the horizontal and vertical lines that would divide the image into thirds horizontally and vertically is visually pleasing.

  4. Rule of thirds - Wikipedia

    en.wikipedia.org/wiki/Rule_of_thirds

    The horizon in the photograph is on the horizontal line dividing the lower third of the photo from the upper two-thirds. The tree is at the intersection of two lines, sometimes called a power point [1] or a crash point. [2] The rule of thirds is a rule of thumb for composing visual art such as designs, films, paintings, and photographs. [3]

    Bake for 1 ⁄ 2 hour. without requiring the use of bulky HTML markup. Please note that these templates do not handle preceding integers (or succeeding units) and the spacing in between, use {} for that: Bake for {{frac|2|1|2}} hours. Bake for 2 + 1 ⁄ 2 hours. As with {}, these templates should not be used in science or mathematical articles.

    Chaussé. A shield may also be party per chevron reversed (inverted), which is like party per chevron except upside down.A section formed by two (straight) lines drawn from the corners of the chief to the point in base is called chaussé (shod), which must be distinguished from the pile, the point of which does not reach the bottom of the shield.

  7. Angle trisection - Wikipedia

    en.wikipedia.org/wiki/Angle_trisection

    Then by the triple-angle formula, cos ⁠ π / 3 ⁠ = 4x 3 − 3x and so 4x 3 − 3x = ⁠ 1 / 2 ⁠. Thus 8x 3 − 6x − 1 = 0. Define p(t) to be the polynomial p(t) = 8t 3 − 6t − 1. Since x = cos 20° is a root of p(t), the minimal polynomial for cos 20° is a factor of p(t). Because p(t) has degree 3, if it is reducible over by Q then ...

  8. Dividing a square into similar rectangles - Wikipedia

    en.wikipedia.org/wiki/Dividing_a_square_into...

    However, there are three distinct ways of partitioning a square into three similar rectangles: [1] [2] The trivial solution given by three congruent rectangles with aspect ratio 3:1. The solution in which two of the three rectangles are congruent and the third one has twice the side length of the other two, where the rectangles have aspect ...

  9. Fraction - Wikipedia

    en.wikipedia.org/wiki/Fraction

    To change a common fraction to decimal notation, do a long division of the numerator by the denominator (this is idiomatically also phrased as "divide the denominator into the numerator"), and round the result to the desired precision. For example, to change ⁠ 1 / 4 ⁠ to a decimal expression, divide 1 by 4 (" 4 into 1 "), to obtain exactly ...
