Questions by the identity their solution uses

A different way into the same bank. Instead of filtering by chapter, pick the formula you want to drill and get every question whose solution actually invokes it — including the ones whose stem never mentions it.

Matrices & Determinants

40 identities across 705 questions, read and tagged one by one. Chapter notes.

Identities used by fewer than 12 questions in a chapter are not listed: a page with four questions on it is not a drill. This chapter yielded 79 distinct identities in all, of which 40 clear that bar.
