  2. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.

  3. Window function - Wikipedia

    en.wikipedia.org/wiki/Window_function

    Typically, window functions are symmetric around the middle of the interval, approach a maximum in the middle, and taper away from the middle. Mathematically, when another function or waveform/data-sequence is "multiplied" by a window function, the product is also zero-valued outside the interval: all that is left is the part where they overlap ...

  4. Programmable calculator - Wikipedia

    en.wikipedia.org/wiki/Programmable_calculator

    These BASIC dialects are optimised for calculator use, combining the advantages of BASIC and keystroke programming. They have little in common with mainstream BASIC. [4] [5] [6] The version for the Ti-89 and subsequent is more fully featured, including the full set of string and character manipulation functions and statements in standard Basic.

  5. Thread angle - Wikipedia

    en.wikipedia.org/wiki/Thread_angle

    In mechanical engineering, the thread angle of a screw is the included angle between the thread flanks, measured in a plane containing the thread axis. [1] This is a defining factor for the shape of a screw thread .

  6. Machine taper - Wikipedia

    en.wikipedia.org/wiki/Machine_taper

    The rate of taper is 1:20 on diameter, in other words 0.600" on diameter per foot, .050" on diameter per inch. Tapers range from a Number 2 to a Number 20. The diameter of the big end in inches is always the taper size divided by 8, the small end is always the taper size divided by 10 and the length is the taper size divided by 2.

  7. Software calculator - Wikipedia

    en.wikipedia.org/wiki/Software_calculator

    GNOME Calculator, a software calculator. A software calculator is a calculator that has been implemented as a computer program, rather than as a physical hardware device. They are among the simpler interactive software tools, and, as such, they provide operations for the user to select one at a time. They can be used to perform any process that ...

  8. Binary angular measurement - Wikipedia

    en.wikipedia.org/wiki/Binary_angular_measurement

    Signed binary angle measurement. Black is traditional degrees representation, green is a BAM as a decimal number and red is hexadecimal 32-bit BAM. In this figure the 32-bit binary integers are interpreted as signed binary fixed-point values with scaling factor 2 −31, representing fractions between −1.0 (inclusive) and +1.0 (exclusive).

  9. Critical taper - Wikipedia

    en.wikipedia.org/wiki/Critical_taper

    The result of these feedbacks is the stable angle of the wedge known as the critical taper. When natural processes (such as erosion, or an increase in load on the wedge due to emplacement of a sea or ice cap) change the shape of the wedge, the wedge will react by internally deforming to return to a critically tapered wedge shape. The critical ...
