    My guess is that he means integrate the trig function secant, sec(x) over a range of x. Probably needs a set of numerical integration routines.

    This may be more than you bargained for, but check out xNumbers. It is an amazing (free) Excel Add-In with a wealth of functions and extremely high (200+ digit) accuracy. The user's guide is phenomenal. I used the routines to create a high accuracy linear matrix solver to solve sets of non-linear equations. Incredible routines. P.S. If you don't know Italian, the code comments won't do you much good.
