The question is:

I did:

Out of all that I've done it seems like it's more along the easy side, but you can never be too sure. Just want to double check my work. Thanks.

I took it as a product rule...it was written exactly as I typed, not as ln(tan(x)). If it was like that, I'd have done 1/tanx * sec^2(x), just as you had. But, since it wasn't written in that way, I got thrown off. Am I missing something here?

You are missing the fact that (ln)(tan x) as a

**product**is meaningless- there is no "x" in the logarithm. It can only mean ln(tan(x)). - Mar 25th 2011, 05:07 AMMarconis
Alright, good to know. Thank you Halls.
