Talk:A-level Mathematics/OCR/C4/Advanced Differentiation

Erm. I started it off. Since we haven't actually done C4 (I've taught it to myself), some of it may only be partially correct. Oh...sorry, I didn't realise that most were taking OCR. I've written this with reference to Edexcel, but I will rewrite it to follow the OCR syllabus if no one else will.
