    solving for 0

    I don't know how to solve for 1-arctan(x)*(2x)/(x^2+1)^2 = 0
    according to a maple the answer is -.7653789267.
    I know the denominator doesn't factor into the solution.
    Thank you for any help.

    you cannot solve this equation by hand ...

    1 - 2x\arctan{x} = 0

    x = \pm 0.7653789267
