Homework Help Overview
The discussion revolves around a calculus problem, specifically focusing on derivatives and inverse functions. Participants are seeking assistance with part (d) of the problem, while also referencing previous parts and the need for clarity in mathematical communication.
Discussion Character
- Exploratory, Assumption checking, Problem interpretation
Approaches and Questions Raised
- Participants are attempting to clarify the requirements of the problem, particularly what is needed for part (d). There are questions about the original poster's understanding and the necessity of showing work. Some participants express confusion about the mathematical notation and the process of typing equations in the forum.
Discussion Status
The discussion is ongoing, with participants offering guidance on the importance of showing work and clarifying misunderstandings. There is a recognition of the challenges faced by the original poster in communicating their problem effectively, but no consensus has been reached on how to proceed with part (d).
Contextual Notes
Participants note that forum rules require some initial work to be shown before seeking help, which has led to discussions about the original poster's approach and the constraints of typing mathematical equations online.

Show your work. Forum rules require you to do some work on your own first, before seeking help.

You said you needed help with part (d), so I assumed you know how to do parts a, b, c .dth257 said:

I'm sorry for misunderstand.
a. f(1)= 0
b. f'(1)= sqrt(5)/5=.447214

Showing your work means not only giving the answers but trying to explain how you got them. What about c)? Once you've got that there is a formula for differentiating inverse functions. See http://en.wikipedia.org/wiki/Inverse_functions_and_differentiation Is that the part you are missing?

I'm sorry I'm a newbie in here. I don't know how to type these mathematical equations in the forum. It would take me few hours to just type all of the work down.( that why i posted the picture instead of type them out) So i just gave out the answer. That's the fastest way i can do.
