Coordinate geometry and vectors flashcards

6 cards drawn from 5 lessons: 3 standard results, 2 recall prompts and 1 spot-the-error card. Lines, circles and vectors, and the facts a diagram question assumes you know. Rate each answer to set a shorter or longer interval before the card is due again.

How the five kinds differ

Standard results ask for a formula or value that may need to be recalled. Definitions ask for a mathematical term to be stated precisely. Recall prompts ask for a rule, condition or method. Check yourself cards contain a short question and answer. Spot the error cards ask you to correct an inaccurate claim.
