单词	parameter(in pure mathematics)
释义	parameter(in pure mathematics) Mathematics A variable taking different values, thereby giving different values to certain other variables. For example, a parameter t could be used to write the solutions of the equation 5x₁ + 4x₂ = 7 as $x_{1} = 3 - 4 t, x_{2} = - 2 + 5 t (t \in ℝ) .$ More generally parameters can be systematically used to describe the general solution of a system of simultaneous linear equations. See also parameterization, parametric equations (of a line in space).
