I'm just trying to solve this

[tex] \int {\sec^3{x} dx [/tex]

2. Relevant equations

[tex] sec^2{x} = 1 + tan^2{x} [/tex]

3. The attempt at a solution

well i was able to simplify it to this:

[tex] \int {\sec{x}*\tan^2{x}} dx + \ln{|\sec{x} + \tan{x}|} [/tex]

but I still was not able to find that new integral
