SL 1.6—Deductive proof Topic Practice
SL 1.6—Deductive proof Topic Practice
Practise constructing algebraic proofs from identities, inequalities, divisibility claims and sequence formulae using clear logical steps.
How this is tested
- expand or factor expressions to prove divisibility, such as showing a difference of squares is a multiple
- prove identities by transforming one side with denominators, cancellation, or division
- set up proof by contradiction with a stated assumption, then derive the required inequality result
