Sophie Ng's answer to Tara's Secondary 4 A Maths Singapore question.
Sophie and Tara, for presentation purposes, you need to include brackets when you write
INT something dx
if the “something” contains two or more terms. For example, if you are integrating x + 5, you must write
INT (x + 5) dx
rather than
INT x + 5 dx.
Missing brackets may lead to deduction of 1 mark due to the presentation inaccuracy.
