  2. Cubic equation - Wikipedia

    en.wikipedia.org/wiki/Cubic_equation

    By Vieta's formulas, s 0 is known to be zero in the case of a depressed cubic, and − ⁠ b / a ⁠ for the general cubic. So, only s 1 and s 2 need to be computed. They are not symmetric functions of the roots (exchanging x 1 and x 2 exchanges also s 1 and s 2 ), but some simple symmetric functions of s 1 and s 2 are also symmetric in the ...

  3. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    In the cases where non-SI units are used, the numerical calculation of a formula can be done by first working out the factor, and then plug in the numerical values of the given/known quantities. For example, in the study of Bose–Einstein condensate , [ 6 ] atomic mass m is usually given in daltons , instead of kilograms , and chemical ...

  4. Cubic centimetre - Wikipedia

    en.wikipedia.org/wiki/Cubic_centimetre

    The displacement can be calculated using the formula = where d is engine displacement, b is the bore of the cylinders, s is length of the stroke and n is the number of cylinders. Conversions. 1 millilitre = 1 cm 3; 1 litre = 1000 cm 3; 1 cubic inch = 16.38706 cm 3.

  5. Centimetre or millimetre of water - Wikipedia

    en.wikipedia.org/wiki/Centimetre_or_millimetre...

    A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...

  6. Volume - Wikipedia

    en.wikipedia.org/wiki/Volume

    Because the volume occupies three dimensions, if the metre (m) is chosen as a unit of length, the corresponding unit of volume is the cubic metre (m 3). The cubic metre is also a SI derived unit. [16] Therefore, volume has a unit dimension of L 3. [17] The metric units of volume uses metric prefixes, strictly in powers of ten. When applying ...

    One cubic zettametre—approximate volume of whole Milky Way including Globes ~5 × 10 68: Volume of the Local Group: 6.7 × 10 71: Volume of the Gemini Void: 1 × 10 72: One cubic yottametre: 1.2 × 10 72: Volume of the Local Void (about 1.4 × 10 24 cubic light years) [24] 3.5 × 10 72: Volume of the Virgo Supercluster [25] 1 × 10 73

  8. List of metric units - Wikipedia

    en.wikipedia.org/wiki/List_of_metric_units

    Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. According to Schadow and McDonald, [ 1 ] metric units, in general, are those units "defined 'in the spirit' of the metric system, that emerged in late 18th century France and was rapidly adopted by scientists and engineers.

  9. Scipione del Ferro - Wikipedia

    en.wikipedia.org/wiki/Scipione_del_Ferro

    There are conjectures about whether del Ferro worked on a solution to the cubic equation as a result of Luca Pacioli's short tenure at the University of Bologna in 1501–1502. Pacioli had previously declared in Summa de arithmetica that he believed a solution to the equation to be impossible, fueling wide interest in the mathematical community.
