The relativistic mass is the sum total quantity of energy in a body or system (divided by c 2).Thus, the mass in the formula = is the relativistic mass. For a particle of non-zero rest mass m moving at a speed relative to the observer, one finds =.
In linear algebra, a column vector with elements is an matrix [1] consisting of a single column of entries, for example, = [].. Similarly, a row vector is a matrix for some , consisting of a single row of entries, = […]. (Throughout this article, boldface is used for both row and column vectors.)
In mathematics, a symmetric matrix with real entries is positive-definite if the real number is positive for every nonzero real column vector , where is the row vector transpose of . [1] More generally, a Hermitian matrix (that is, a complex matrix equal to its conjugate transpose) is positive-definite if the real number is positive for every nonzero complex column vector , where denotes the ...
kilogram meter squared (kg⋅m 2) intensity: watt per square meter (W/m 2) imaginary unit: unitless electric current: ampere (A) ^ Cartesian x-axis basis unit vector unitless current density: ampere per square meter (A/m 2) impulse: kilogram meter per second (kg⋅m/s)
M is molar mass of the substance, and thus may be calculated as a product of particle mass, m, and Avogadro constant, N A: =. For diatomic nitrogen ( N 2 , the primary component of air ) [ note 1 ] at room temperature ( 300 K ), this gives
In integral calculus, integration by reduction formulae is a method relying on recurrence relations.It is used when an expression containing an integer parameter, usually in the form of powers of elementary functions, or products of transcendental functions and polynomials of arbitrary degree, can't be integrated directly.

where x, y, and z axes are aligned to the principal axes of the ellipsoids, and m * x, m * y and m * z are the inertial effective masses along these different axes. The offsets k 0,x, k 0,y, and k 0,z reflect that the conduction band minimum is no longer centered at zero wavevector. (These effective masses correspond to the principal components ...
