# Cosecant
|

$$ y = \csc(x) $$

|

|
||||
$$ \csc(x) = \frac{1}{\sin(x)} $$
|
||||
|
||||
Because cosecant is the reciprocal of sine, when $\sin{x} = 0$, then cosecant is undefined. $|\sin$| is never *greater than* 1, so secant is never *less than* 1 in absolute value. When the graph of cosine crosses the x axis, an asymptote for a matching graph of secant will appear there.
|
||||
|
||||
The general form of secant is:
|
||||
$$ y = A\sec(B{x} - C) + D $$
|
||||
$A$, $B$, $C$, and $D$ will have similar meanings to the secant functions as they did to the sine and cosine functions.
