# Tricky Integration C1 Watch

1. C1 tricky integration question. Despite even my clever sibling questioning these questions in the book I've came to think I'm stupid for not knowing. It is Exersise 8E Question 4 and 5 in the integration section. Please help. I understand you integrate x^2 to get your answer and then integrate f2(x) to get the next answer. But why? Plz help..
2. More people would be able to help if you posted the question.

3. You integrate the differential to get back to the original equation, e.g. . You do the same for Q4b it's asking for an expression so you want a formula for , you should be able to spot the pattern after finding although you can do more if you can't see it clearly. Q5 is the same.
