What are you stuck on? How much have you done?
3. For the first part, use applications of the chain rule.
4. Hey bro, thanks for replying.
I'm relatively new to this chapter. May i know how do you differentiate y=f(x), and x=e^u to prove dy/du?
I need little of guidelines regarding to that.
Thank you mate. Cheers

You know that right?

You want and by the chain rule that is as

Also
Use dy/dx in terms of e^u and show what the question asks for.
7. Correct me if I am wrong
Du/Dx =e^u

However, may I know how to differentiate y=f(x) making it in terms of dy/du?

Hey ,
May I know what is FP1/FP2?
I am taking CIE A-levels further maths.
Perhaps you're referring to Edexel or OCR Further maths?
