Hi, I kow about the chain rule and such; but there I cannot solve a problem in my calc textbook.(adsbygoogle = window.adsbygoogle || []).push({});

y = Arctan(x^2-1) + Arccscx, x > 1.

Answer on back says 0; but my answer didn't go to 0. BTW, this is just one problem from a HW assignment so this shouldn't count as cheating.

Thanks!
