The first semester of calculus covers differentiation while the second focuses on integration.

paired with 'integration' as the two branches of calculus

同義詞

    the full formal name for the field; 'differentiation' is a shorter, everyday alternative among math students

反義詞
  • integration

    often used as the counterpart field (integral calculus)

文法句型

differentiation and integration

用法筆記

This sense refers to the field or subdiscipline itself rather than the individual operation (sense 4). In practice, most textbooks use 'differentiation' for both meanings, and context tells them apart: 'I studied differentiation' (the field) vs. 'perform differentiation on this function' (the operation).

6. a teaching approach in which a teacher uses different tasks, materials, or level

6.名詞B2

differentiation in the classroom

differentiation by [ability/level]
