The input of a vector-valued function could be a scalar or a vector. The dimension of the domain is not defined by the dimension of the range. ==Example== A common example of a vector-valued function is one that depends on a single real number parameter ''t'', often representing time, producing a vector v(''t'') as the result. In terms of the standard unit vectors i, j, k of Cartesian 3-space, these specific type of vector-valued functions are given by expressions such as *$\backslash mathbf(t)=f(t)\backslash mathbf+g(t)\backslash mathbf$ or *$\backslash mathbf(t)=f(t)\backslash mathbf+g(t)\backslash mathbf+h(t)\backslash mathbf$ where ''f''(''t''), ''g''(''t'') and ''h''(''t'') are the coordinate functions of the parameter ''t''. The vector r(''t'') has its tail at the origin and its head at the coordinates evaluated by the function. The vector shown in the graph to the right is the evaluation of the function near ''t''=19.5 (between 6π and 6.5π; i.e., somewhat more than 3 rotations). The spiral is the path traced by the tip of the vector as t increases from zero through 8π. Vector functions can also be referred to in a different notation: *$\backslash mathbf(t)=\backslash langle\; f(t),\; g(t)\backslash rangle$ or *$\backslash mathbf(t)=\backslash langle\; f(t),\; g(t),\; h(t)\backslash rangle$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vector-valued function」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
