The reciprocal function referred here is the inverse trigonometric function identities. The inverse or reciprocal function of sec x is 1/cos x. Replacing secant with cosine, the equation becomes:
y = (2/cos x) - 3
To graph this, assign random values of x, then you'll get corresponding values of y. Plot the points and connect them together. The graph is shown in the attached picture.

Answer:
When the plane makes its turn to fly southeast, it makes a 45º angle at point a, making angle abc also equal to 45º.
Line ab is the 2 miles southeast the plane flies.
Line ac = line cb
sine (45º) = opposite / hypotenuse = cb / 2
.70711 = cb / 2
cb = 1.41422 miles = line ac
Line cs = 3 - 1.41422 = 1.58578
Line x^2 = cs^2 + cb^2
Line x^2 = 2.5146982084 + 2.0000182084
Line x^2 = 4.5147
Line x = 2.1248
