    Newton's Method

    Use Newton's method to approximate the indicated root of the equation correct to six decimal places.

    x^4+x-4=0, [1,2]

    Okay, so the answer I got for this was 1.283764, however I don't believe that is correct. Newton's method is straightforward enough, so I'm assuming I plugged something in wrong or make a careless error...

    Your answer for the positive root is very accurate!

    That's quite odd, because it was marked wrong on a quiz... :0

    To 6 decimal places "of accuracy", it's 1.283782,

    maybe that's the problem.
