FP3.5.2 - Use of vectors in problems

Use of vectors in problems Students may be required to use equivalent cartesian forms involving points, lines and planes. also.; The equation of a line in the form Applications to include (r − a) × b = 0. (i) distance from a point to a plane, (ii) line of intersection of two planes, (iii) shortest distance between two skew lines.

Use fp3.5.2 - use of vectors in problems to connect the rule to the data and decision in the question.

This matters because fp3.5.2 - use of vectors in problems determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp3.5.2 - use of vectors in problems to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP3.5.2 - Use of vectors in problems is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
