complex hamtâft (#) Fr.: complexe 1) General: (n. & adj.) A whole comprised of many elements.
→ complex wave. From Fr. complexe, from L. complexus "surrounding, encompassing," p.p. of complecti "to embrace, encompass, include," from → com- "together" + plectere "to weave, twine." Hamtâft, from ham- "together," → com- + tâft past stem of tâftan, tâbidan "to twist, to spin, to bend, to crook," p.p. tâftah "spun, silk or linen cloth," loaned into E. taffeta (from O.Fr. taffetas, from It. taffeta); similarly Gk. tapetion "little carpet" is probably from this Iranian origin (from which tapestry, tapis); Proto-Ir. *tap- "to spin," related to tan-, tanidan "to spin; to stretch," → tension. |
complex conjugate hamyuq-e hamtâft (#) Fr.: conjugé A → complex number in which the → real part of the number remains the same, but i is replaced by -i. For example, the complex conjugate of x + iy is x - iy. Same as → conjugate complex number. |
complex dynamical variable vartande-ye tavânik-e hamtâft Fr.: variable dynamique complexe A → dynamical variable which has an → imaginary number part. |
complex Fourier series seri-ye Fourier-ye hamtâft Fr.: série de Fourier complexe The complex notation for the → Fourier series of a function f(x). Using → Euler's formulae, the function can be written in cimplex form as f(x) = Σ c_{n} e^{inx} (summed from -∞ to ∞), where the → Fourier coefficients are c_{n} = (1/2π)∫ f(x) e^{-inx} dx (integral from -π to +π). → complex; → Fourier series. |
complex fraction barxe-ye hamtâft Fr.: fraction complexe A fraction in which the → numerator or → denominator, or both, contain fractions. For example (3/5)/(6/7). Also called → compound fraction. |
complex molecule molekul-e hamtâft Fr.: molécule complexe A molecule in the → interstellar medium comprising at least six atoms (e.g. Herbst & van Dishoeck, 2009, ARA&A). |
complex number adad-e hamtâft (#) Fr.: nombre complexe Any number of the form u = a + bi, where a and b are → real numbers and i imaginary, i.e. i^{2} = -1. |
complex organic molecule (COM) molekul-e orgânik-e hamtâft Fr.: molécule organique complexe A → complex molecule containing C, H, O, and N atoms and involved in life developing processes. See also → organic molecule. |
complex population porineš-e hamtâft Fr.: population complexe Same as → composite population. → complex; → population. |
complex wave mowj-e hamtâft (#) Fr.: onde complexe A wave that is composed of several frequencies. |
conjugate complex number adad-e hamtâft hamyuq (#) Fr.: nombre complexe conjugé The conjugate of a → complex number, expressed by ū = a - bi. The complex number and its conjugate have the same real part. Same as → complex conjugate. |
