 Gaussian   گاؤسی   Gaussi (#)Fr.: gaussien   Of or relating to Carl Friedrich Gauss or his mathematical theories of magnetism, electricity, astronomy, or probability. → Gaussian distribution; → Gaussian profile.→ gauss. Gaussian distribution   واباژش ِ گاؤسی   vâbâžeš-e Gaussi (#)Fr.: distribution gaussienne   A theoretical frequency distribution for a set of variable data, usually represented by a bell-shaped curve with a mean at the center of the curve and tail widths proportional to the standard deviation of the data about the mean.→ Gaussian; → distribution. Gaussian elimination   اسانش ِ گاؤسی   osâneš-e GaussiFr.: élimination de Gauss   A method of solving a matrix equation of the form A x = b, where A is a matrix and x and b are vectors. The process consists of two steps, first reducing the elements below the diagonal to 0 and second, back substituting to find the solutions.→ Gaussian; → elimination. Gaussian function   کریای ِ گاؤس   karyâ-ye GaussFr.: fonction de Gauss   The function e-x2, whose integral in the interval -∞ to +∞ gives the → square root of the → number pi: ∫e-x2dx = √π. It is the function that describes the → normal distribution.→ Gaussian; → function. Gaussian gravitational constant   پایای ِ گرانشی ِ گاؤس   pâyâ-ye gerâneši-ye GaussFr.: constante gravitationnelle de Gauss   The constant, denoted k, defining the astronomical system of units of length (→ astronomical unit), mass (→ solar mass), and time (→ day), by means of → Kepler's third law. The dimensions of k2 are those of Newton's constant of gravitation: L 3M -1T -2. Its value is: k = 0.01720209895.→ Gaussian; → gravitational; → constant. Gaussian integer   درسته‌ی ِ گاؤس   doroste-ye GaussFr.: entier de Gauss   A → complex number whose → real and → imaginary parts are both integers.→ Gaussian; → integer. Gaussian profile   فراپال ِ گاؤسی   farâpâl-e GaussiFr.: profile gaussien   The shape of a curve representing a normal distribution.→ Gaussian; → profile. Gaussianity   گاؤسیگی   GaussigiFr.: gaussienité   Math.: The condition of having → Gaussian distribution. The extent to which something is Gaussian.→ Gaussian + → -ity.
