Discussion Overview

The discussion revolves around finding the nth derivative of the function f(x) = (3x + 7)/(x + 2). Participants explore methods for deriving this result, including potential simplifications or formulas applicable to the problem.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant expresses their need for assistance in calculating the nth derivative of the given function.
  • Another participant questions whether the original poster can calculate the first derivative, implying that this may be a necessary step.
  • The original poster confirms their ability to find the first derivative but seeks a direct method for the nth derivative.
  • A suggestion is made to compute the first several derivatives to identify a potential pattern in the derivatives.
  • A later reply proposes a formula for the nth derivative: [((-1)^n)(n!)]/[(x+2)^(n+1)], although it is unclear if this is universally accepted or if it requires further verification.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the method for finding the nth derivative, and multiple approaches are suggested without resolution.

Contextual Notes

Participants have not fully explored the implications of their proposed formula, and there may be assumptions regarding the validity of the pattern observed in the derivatives.

Hey guys,
I'm fairly new to the topic of nth derivative.
can some one please help me in solving this problem?
f(x)= (3x+7)/(x+2).
it would be a great help.
Thanks

Welcome to physicsforums. You forgot to state what your question is. Are you able to, at least, calculate the first derivative?

yeah dude I can find the first derivative ... I need to find the nth derivative directly ... so is there some simplification or formula to find the nth derivative?
 
I recommend taking the first, second, and third derivative.
Perhaps you can post back if you do not see a pattern emerging?
 
Take the first several derivatives to help find a pattern. This is what I found:

the nth derivative is [((-1)^n)(n!)]/[(x+2)^(n+1)
