Very similar to this one:
\n" ); document.write( "===================
\n" ); document.write( "If tan theta=3/2 and cos theta<0, find the other five trig functions of theta
\n" ); document.write( " ----------
\n" ); document.write( " tan = y/x = 3/2
\n" ); document.write( "r = sqrt(y^2 + x^2) = sqrt(13)
\n" ); document.write( " -----
\n" ); document.write( " tan + and cos < 0 --> Q3
\n" ); document.write( " ---
\n" ); document.write( " sin = y/r = 3/sqrt(13) --> -3sqrt(13)/13
\n" ); document.write( " cos = x/r = 2sqrt(13)/13
\n" ); document.write( " cot = 1/tan
\n" ); document.write( " sec = 1/cos
\n" ); document.write( " csc = 1/sin
\n" ); document.write( "
\n" );
