## Trigonometry (11th Edition) Clone

The equation is: $f(x) = sec~2x$
The graph has the basic shape of a secant graph. However, compared with the standard secant graph, the first positive asymptote occurs at $x = \frac{\pi}{4}$ instead of $x = \frac{\pi}{2}$. Therefore, we need to include an angle of $2x$ in the function. The equation is: $f(x) = sec~2x$
