  2. Stretched exponential function - Wikipedia

    en.wikipedia.org/wiki/Stretched_exponential_function

    With a stretching exponent β between 0 and 1, the graph of log f versus t is characteristically stretched, hence the name of the function. The compressed exponential function (with β > 1) has less practical importance, with the notable exception of β = 2, which gives the normal distribution.

  3. List of open-source software for mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_open-source...

    The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.

  4. Stretch factor - Wikipedia

    en.wikipedia.org/wiki/Stretch_factor

    The stretch factor is important in the theory of geometric spanners, weighted graphs that approximate the Euclidean distances between a set of points in the Euclidean plane. In this case, the embedded metric S is a finite metric space, whose distances are shortest path lengths in a graph, and the metric T into which S is embedded is the ...

  5. Function of several real variables - Wikipedia

    en.wikipedia.org/wiki/Function_of_several_real...

    The image of a function f(x 1, x 2, …, x n) is the set of all values of f when the n-tuple (x 1, x 2, …, x n) runs in the whole domain of f.For a continuous (see below for a definition) real-valued function which has a connected domain, the image is either an interval or a single value.

  6. Superellipse - Wikipedia

    en.wikipedia.org/wiki/Superellipse

    Examples of superellipses for =, =. A superellipse, also known as a Lamé curve after Gabriel Lamé, is a closed curve resembling the ellipse, retaining the geometric features of semi-major axis and semi-minor axis, and symmetry about them, but defined by an equation that allows for various shapes between a rectangle and an ellipse.

  7. Mohr's circle - Wikipedia

    en.wikipedia.org/wiki/Mohr's_circle

    In this example, when the rectangle is horizontal, the stresses are given by [] = []. The corresponding Mohr's circle representation is shown at the bottom. The magnitude of the principal stresses are the abscissas of the points C {\displaystyle C} and E {\displaystyle E} (Figure 6) where the circle intersects the σ n {\displaystyle \sigma ...

  8. Range of a projectile - Wikipedia

    en.wikipedia.org/wiki/Range_of_a_projectile

    The first solution corresponds to when the projectile is first launched. The second solution is the useful one for determining the range of the projectile. Plugging this value for (t) into the horizontal equation yields = ⁡ ⁡ Applying the trigonometric identity
