Inverse Trig function derivative

  1. Nov 22, 2007 #1
    1. The problem statement, all variables and given/known data


    arctan ([tex]\sqrt{3x^2 -1}[/tex])

    then dy/dx

    Well I know that the derivative of arctanx is

    1/ 1 + x ² but when I got something other then simply x I don't know how to proceed
