ok, so i'm doing a calc assignment, and the whole assignment is done except for one question, the rest of the answers check properly on my graphing calculator both with nDeriv and the tangent function. this question shouldnt be so hard, but i must be missing something. could use a bit of help.(adsbygoogle = window.adsbygoogle || []).push({});

question:

[tex]y=x\tan3x+\csc^2(1-x^3)[/tex], find [tex]y\prime[/tex]

i've tried this one in several ways, rewriting it in terms of sin and cos, all sorts of things, and i keep coming out with essentially the same answer.

[tex]y\prime=\tan3x+3x\sec^2{3x}+6x^2\csc^2(1-x^3)\cot(1-x^3)[/tex]

to me it looks right, but it doesnt check out on the calculator, so i'm assuming i'm missing something, and would appreciate a hand, cheers.

::edit:: woops, had to fix second equation, had minus instead of plus, but it still doesnt work.
