1.3.6 - Resultant vectors

Be able to find the resultant of two coplanar vectors at any angle to each other by drawing, and at right angles to each other by calculation.

Use - resultant vectors to connect the rule to the data and decision in the question.

This matters because - resultant vectors determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - resultant vectors to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Resultant vectors is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
