$\displaystyle\lim_{x\to\pi/2^-}\left(x-\frac\pi2\right)\sec x=\lim_{x\to\pi/2^-}\frac{x-\frac\pi2}{\cos x}$

Since $\cos\dfrac\pi2=0$ , this limit yields the indeterminate form $\dfrac00$ . By L'Hopital's rule, we have

$\displaystyle\lim_{x\to\pi/2^-}\dfrac1{-\sin x}$

and since $\sin\dfrac\pi2=1$ , we end up with -1 as the limit.

Well, from what I can tell, we just have to combine like terms, meaning that all of the terms that have the same variables can be combined:

F = (ABC + ABC) + A'B

F = 2ABC + A'B

If that's not what you meant, or if you have questions, feel free to let me know! :)
