What is sin(x) if the sides of an isosceles triangle (not right) are sin(x), cos(x), tan(x)?
\n" ); document.write( "--------------
\n" ); document.write( "sin(x) = cos(x) if x = pi/4
\n" ); document.write( "--> sin(x) = sqrt(2)/2
\n" ); document.write( "------------
\n" ); document.write( "Or cos(x) = tan(x)
\n" ); document.write( "--> sin(x) = (sqrt(5) - 1)/2
\n" ); document.write( " \n" ); document.write( "

\n" );
