Best ResponseYou've already chosen the best response.0\[y = \sin[x  \tan (\frac{ \Pi }{ 4 }x^{66})] + x ^{\frac{ 1 }{ 1 + 66\Pi }}\]

Best ResponseYou've already chosen the best response.0if you cant see the exponent part at the end, its: \[\frac{ 1 }{ 1+66\Pi }\]

Best ResponseYou've already chosen the best response.0im currently at this step: \[\frac{ 66\Pi }{ 4} + \frac{ 1 }{ 1 + 66\Pi }\]

Best ResponseYou've already chosen the best response.0i got this for y prime: \[y' = \cos[x  \tan(\frac{ \pi }{ 4 }x^{66})](1  \sec^2(\frac{ \pi }{ 4 }x^{66}))(\frac{ 66\pi }{ 4 }x^{65}) + \frac{ 1 }{ 1+66\pi }x^\frac{ 1 }{ 1+66\pi }1\]

Best ResponseYou've already chosen the best response.0So 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

Best ResponseYou've already chosen the best response.0plugged 1 in.. \[y'(1) = 1(1)(\frac{ 66\pi }{ 4 })(\frac{ 1 }{ 1+ 66\pi })\]

Best ResponseYou've already chosen the best response.0the factoring is the confusing part... how am i supposed to get it to 99pi

Best ResponseYou've already chosen the best response.0unless the steps i did to get it to that point were incorrect...i dont think so

Best ResponseYou've already chosen the best response.0Oh that last term should be addition.. my bad. The way that you have it originally wrote out.

Best ResponseYou've already chosen the best response.1What the **** kind of teacher give you question like that?!? Or did you make up this question on your own?

Best ResponseYou've already chosen the best response.0the 4's cancel out..but then what? lol

Best ResponseYou've already chosen the best response.0i guess the neg sign could be the neg sign in the answer: 99pi

Best ResponseYou've already chosen the best response.0What we currently have = 51.83147906... 99pi = 311.0176727 Hmmm something isn't right, that doesn't equal 99pi

Best ResponseYou've already chosen the best response.0i guess i could submit this answer wrong and get a similar question with different values

Best ResponseYou've already chosen the best response.0or that could make things worse

Best ResponseYou've already chosen the best response.1According to WolframAlpha, the answer is 102.68 or \[133 \pi+\frac{1}{1+66 \pi}\] 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
