Mathematica and integrate

I am sort of exploring mathematica now:

After I used

Code:



f = Tan(x)



Integrate[f, x]

It gave:

Code:

(Tan x^2 )/ 2

But I am expecting result for result:

[/code]
ln | sec x |
[/code]

Anyone has any idea why the different? Can I force it to achieve my expected format? Any suggestion/pointers to other resource are welcome!
