  • #1

Main Question or Discussion Point

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)
