: Students had to sketch circles and half-lines, such as the locus , which represents a circle with center and radius
Always check if denominator changes sign – use critical values. 2012 njc prelim h2 math
Paper 1 tested the core topics intensely. There was a noticeable emphasis on and curve sketching , which are often weak points for students who rely on the graphic calculator too heavily. : Students had to sketch circles and half-lines,
Some questions are overly convoluted. Focus on: such as the locus
Curve ( C: x = t^2, y = t^3 - 3t )
They may give two lines (y on x and x on y) and ask for correlation coefficient.
Based on the exam solutions, the 2012 paper featured several classic H2 Math challenges:
