Translation guide
The cross product is a mathematical operation on two vectors in three-dimensional space that produces a third vector perpendicular to both. This guide covers how to express the concept in Japanese, primarily in mathematical contexts.
cross product (mathematics)
The vector operation producing a perpendicular vector
Standard term for cross product in mathematics and physics. Literally 'outer product'.
In mathematical discussions, 外積 is the default term. クロス積 is understood but may sound like a direct translation. Use 外積 in formal writing.
ベクトルAとBの外積を計算してください。
Please calculate the cross product of vectors A and B.
Loanword from English, used in some contexts, but less common than 外積.
