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

    Re: Calculus Problem!!

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

    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 dont 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.
