If I remember correctly, there is only one "Trigonometric Function" block in Simulink. Just double click the block and change the function from sin to sec.

Well, then, just use cos and route the result through a Math Function block with the Function set to "reciprocal with Exact method", since the secant is the reciprocal of the cosine.
