Simple Calc Problem: Arctan

  1. Dec 7, 2009 #1
    1. The problem statement, all variables and given/known data

    Find the derivative of the function. Simplify if possible.

    y = arctan (x + sqrt(1+x^2))

    2. Relevant equations

    I know there's something like... y = arctan(x) = ( x = tan(y) )

    I'm not sure how to manipulate it...

    3. The attempt at a solution

    I'm not really sure how to start, any help would be greatly appreciated.

    Thanks!

    You probably know the derivative of arctan. If so, just differentiate it using the chain rule and do some algebra to simplify it.
