The abbreviation for the cosecant function is 
}{1\ +\ \csc(x)}\ \equiv^?\ \sin(x))
The cosecant is the reciprocal of the sine:
}{1\ +\ \frac{1}{\sin(x)}}\ \equiv^?\ \sin(x))
Apply the common denominator in the denominator of the complex fraction
}{\frac{1\ +\ \sin(x)}{\sin(x)}}\ \equiv^?\ \sin(x))
Invert the denominator and multiply:
\)\(\frac{\sin(x)}{1\ +\ \sin(x)}\)\ \equiv^?\ \sin(x))
\ \equiv\ \sin(x)\ \ \ )
