The scalar projection is a scalar, equal to the length of the orthogonal projection of $\backslash mathbf$ on $\backslash mathbf$, with a negative sign if the projection has an opposite direction with respect to $\backslash mathbf$. Multiplying the scalar projection of $\backslash mathbf$ on $\backslash mathbf$ by $\backslash mathbf$ converts it into the above-mentioned orthogonal projection, also called vector projection of $\backslash mathbf$ on $\backslash mathbf$. ==Definition based on angle ''θ''== If the angle $\backslash theta$ between $\backslash mathbf$ and $\backslash mathbf$ is known, the scalar projection of $\backslash mathbf$ on $\backslash mathbf$ can be computed using :$s\; =\; |\backslash mathbf|\; \backslash cos\; \backslash theta\; .$ 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「Scalar projection」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.
