Pure maths 07syl.

No, the topics about finding arc-length by integration had been deleted since 2006
there are some other topic that had been removed, you may take a look of it
(i) Backwork induction.
(ii) Complex factorization of the form z^n + 2ncost + 1
(iii) Vector space (whole chapter)
(iv) Finding surface area, arc-length and area in polar coordinate form by integration.
(v) Improper integrals
(iv) 3 dimensional geometry.

1 考試局2007pure maths課程綱要積分法的應用
注釋中只有平面圖形面積及立體體積計算
2
Breakthrough Pure Mathematics – Calculus and Coordinate. Geometry (3rd Edition) – Y.L. Ng & K.M. Pang
中沒有計arc. length的章節
所以應該不會列入2007年高考範圍
