# Math Help - Can this function be simplified further??

1. ## Can this function be simplified further??

f'​(x) = ex(tanx+sec2x-x-1)

2. ## Re: Can this function be simplified further??

Hey jayjay55531.

Hint: Consider the relationship between tan^2(x) and (sec^2(x)).

3. ## Re: Can this function be simplified further??

Hmmm. Well sec2(x) = 1+tan2(x), right? so.... I'd end up with ex(tanx+tan2x-x), right?
So then is that the most simplified it can be?

Thats pretty simplified: I wouldn't try and over-do it (it looks good).

Alright. Thanks so much for your help!
