the following pdf document contains your answer.

\n" ); document.write( "the sin function is positive in the first 2 quadrants.
\n" ); document.write( "the csc function is the reciprocal of the sin function and is also positive in the first 2 quadrants.
\n" ); document.write( "sin = opposite / hypotenuse
\n" ); document.write( "csc = hypotenuse / opposite.
\n" ); document.write( "opposite = vertical line of the triangle formed by the angle.
\n" ); document.write( "in the first and second quadrants, opposite side is positive.
\n" ); document.write( "in the third and fourth quadrants, opposite side is negative.
\n" ); document.write( "hypotenuse is always positive.
\n" ); document.write( "+/+ = +
\n" ); document.write( "+/- or -/+ = -
\n" ); document.write( "sin and csc are positive in quadrants 1 and 2.
\n" ); document.write( "sin and csc are negative in quadrants 3 and 4.
