  • Addition theorem — In mathematics, an addition theorem is a formula such as that for the exponential function: e x + y = e x · e y that expresses, for a particular function f , f ( x + y ) in terms of f ( x ) and f ( y ). Slightly more generally, as is the case… …   Wikipedia

  • addition theorem — noun : a formula or rule that expresses algebraically a function of the sum of two arguments in terms of the same or related functions of the separate arguments [as sin (x + y) = sin x cos y + sin y cos x] …   Useful english dictionary

  • Addition — is the mathematical process of putting things together. The plus sign + means that two numbers are added together. For example, in the picture on the right, there are 3 + 2 apples meaning three apples and two other apples which is the same as… …   Wikipedia

  • Addition of natural numbers — is the most basic arithmetic binary operation. The operation addition takes two natural numbers, the augend and addend, and produces a single number, the sum. The set of natural numbers will be denoted by N, and 0 will be used to denote the… …   Wikipedia

  • Mordell–Weil theorem — In mathematics, the Mordell–Weil theorem states that for an abelian variety A over a number field K, the group A(K) of K rational points of A is a finitely generated abelian group, called the Mordell Weil group. The case with A an elliptic curve… …   Wikipedia

  • Deduction theorem — In mathematical logic, the deduction theorem is a metatheorem of first order logic.[1] It is a formalization of the common proof technique in which an implication A → B is proved by assuming A and then proving B from this assumption.… …   Wikipedia

  • Newton's theorem of revolving orbits — Figure 1: An attractive force F(r) causes the blue planet to move on the cyan circle. The green planet moves three times faster and thus requires a stronger centripetal force, which is supplied by adding an attractive inverse cube force. The …   Wikipedia
