Then the function f(t) = −ωt + θ has slope −ω, which is called a negative frequency. But when the function is used as the argument of a cosine operator, the result is indistinguishable from cos(ωt − θ). Similarly, sin(−ωt + θ) is indistinguishable from sin(ωt − θ + π). Thus any sinusoid can be represented in terms of a ...
The original gratis/libre distinction concerns software (i.e., code), with which users can potentially do two [citation needed] kinds of things: 1. access and use it; and 2. modify and re-use it. "Gratis" pertains to being able to access and use the code, without a price-barrier, while "libre" pertains to being allowed to modify and re-use the ...
The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; [2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of ...
Thus the measured value of the average one-way speed is dependent on the method used to synchronize the start and finish clocks. This is a matter of convention. The Lorentz transformation is defined such that the one-way speed of light will be measured to be independent of the inertial frame chosen. [8]
The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an incompressible flow. The medium can be a gas or a liquid.
Thus, a Phonetic Roman Alphabet converter is also available on the Hindi Wikipedia, so the Roman keyboard can be used to contribute in Hindi, without having to use any special Hindi-typing software. Hindi Wikipedia is the second most popular Wikipedia in India after the English version. More than 85% of Wikipedia pageviews from India are to the ...

A PDF page description can use a matrix to scale, rotate, or skew graphical elements. A key concept in PDF is that of the graphics state, which is a collection of graphical parameters that may be changed, saved, and restored by a page description. PDF has (as of version 2.0) 25 graphics state properties, of which some of the most important are:
