The
secant was defined by the
reciprocal identity
Notice that the function is undefined when the cosine is 0, leading to vertical asymptotes at
etc. Because the cosine is never more than 1 in absolute value, the secant, being the reciprocal, will never be less than 1 in absolute value.
We can graph
by observing the graph of the cosine function because these two functions are reciprocals of one another. See
[link] . The graph of the cosine is shown as a dashed orange wave so we can see the relationship. Where the graph of the cosine function decreases, the graph of the
secant function increases. Where the graph of the cosine function increases, the graph of the secant function decreases. When the cosine function is zero, the secant is undefined.
