    \[y = \sin[x - \tan (\frac{ \Pi }{ 4 }x^{66})] + x ^{\frac{ 1 }{ 1 + 66\Pi }}\]

    if you cant see the exponent part at the end, its: \[\frac{ 1 }{ 1+66\Pi }\]

    im currently at this step: \[\frac{ -66\Pi }{ 4} + \frac{ 1 }{ 1 + 66\Pi }\]

    i got this for y prime: \[y' = \cos[x - \tan(\frac{ \pi }{ 4 }x^{66})](1 - \sec^2(\frac{ \pi }{ 4 }x^{66}))(\frac{ 66\pi }{ 4 }x^{65}) + \frac{ 1 }{ 1+66\pi }x^\frac{ 1 }{ 1+66\pi }-1\]

    So what i tried to do is... After you get a common denominator and all that jazz.. you have something that looks like a polynomial in the numerator. And I'm not seeing it factor nicely :( at least not in any way that will cancel with the denominator. Hmmm

    plugged 1 in.. \[y'(1) = 1(-1)(\frac{ 66\pi }{ 4 })(\frac{ 1 }{ 1+ 66\pi })\]

    the factoring is the confusing part... how am i supposed to get it to -99pi

    unless the steps i did to get it to that point were incorrect...i dont think so

    i guess the neg sign could be the neg sign in the answer: -99pi

    What we currently have = -51.83147906... -99pi = -311.0176727 Hmmm something isn't right, that doesn't equal -99pi

    According to WolframAlpha, the answer is -102.68 or \[1-33 \pi+\frac{1}{1+66 \pi}\] http://www.wolframalpha.com/input/?i=derivative+of++sin%28x+-+tan%28pi+%2F+4+x%5E66%29%29+%2B+x%5E%28%281%29%2F%281%2B66+pi%29%29+when+x+%3D+1
