    Images do not change color when part of a link. Copy-paste as text duplicates the formula's source code, copy-paste as image is not supported in many programs e.g. Word. PNG: Robust. Little overhead in a browser. Native MathML: Robust and standard-compliant. Little overhead in Firefox. Supported by screen readers.

    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.

  4. Tsiolkovsky rocket equation - Wikipedia

    en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

    A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...

  5. Quadratic formula - Wikipedia

    en.wikipedia.org/wiki/Quadratic_formula

    The quadratic formula is exactly correct when performed using the idealized arithmetic of real numbers, but when approximate arithmetic is used instead, for example pen-and-paper arithmetic carried out to a fixed number of decimal places or the floating-point binary arithmetic available on computers, the limitations of the number representation ...

    If there is a problem, then paste into Excel2Wiki first, and copy the wikitext. Sometimes rates need multiple decimal places to separate the locations from each other when the rate column is sorted. For example: List of countries by firearm-related death rate. Here is how to round off to 3 decimal places without changing the single "0" to 0.000.

    en.wikipedia.org/wiki/Maxwell's_equations

    Maxwell's equations on a plaque on his statue in Edinburgh. Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, electric and magnetic circuits.

  9. Cut, copy, and paste - Wikipedia

    en.wikipedia.org/wiki/Cut,_copy,_and_paste

    The inversion from verb—object to object—verb on which copy and paste are based, where the user selects the object to be operated before initiating the operation, was an innovation crucial for the success of the desktop metaphor as it allowed copy and move operations based on direct manipulation.
