Vectors in 2012 NJC Prelims were not about rote formulas. One specific problem gave two skew lines ( L_1 ) and ( L_2 ). Instead of just asking for the shortest distance (which is standard), the paper asked:
This question was a masterclass in domain restriction. While most schools taught the standard method, NJC introduced a composite function involving a modulus inside a square root. 2012 njc prelim h2 math
