Alternative forms
Unless the question specifies otherwise, accept equivalent forms.
As this is an international examination, accept all alternative forms of notation.
In the markscheme, equivalent numerical and algebraic forms will generally be written in brackets immediately following the answer.
In the markscheme, simplified answers, (which candidates often do not write in examinations), will generally appear in brackets. Marks should be awarded for either the form preceding the bracket or the form in brackets (if it is seen).
Example: for differentiating f ( x) 2sin (5 x 3) , the markscheme gives: f ( x)

2cos (5 x 3) 5

10cos (5 x 3)

A1

Award A1 for 2cos (5 x 3) 5 , even if 10cos(5 x 3) is not seen.
