It is probable not surprising and something that I had anticipated that the thorough investigation of the parabola, locus problems and eventually conics have been removed. It is disappointing, given some of great problem-solving skills that this develops in our students.
Circle Geometry has now moved completely to Extension 2 Mathematics, which represents the overall reduction in Coordinate Geometry.
So long curve sketching. Whilst functions remain a significant part of the 2 unit course and there is still a focus on Trig graphs in Extension 1, the more complex analysis of graphing has been diminished.
Motion seems to have been moved completely from Extension 1 Mathematics to Extension 2 Mathematics (despite being kept in the glossary of terms for Extension 1 - maybe an attention to detail thing??)
Volumes only seem to be investigated superficially in Extension 1, with no harder problems in Extension 2, although this could come into the integration parts of the course.
There are of course additions to the courses. Namely, Statistics in the calculus courses and Matrices (vectors) being introduced to Extension 2 Mathematics.
