sec x tan x - ¡ì sec x tan^2(x) dx

= sec x tan x + ¡ì sec x dx - ¡ì sec^3(x) dx

What I don't understand about your question is what is

¡ì ?

i just want to know if those two equations are equal, if yes, how did one go to the other.

I'm not sure what your symbols stand for either. Something didn't translate to ASCII very well when you did the paste.
