what is the real value of COS 30Degrees
\n" ); document.write( "------
\n" ); document.write( "Draw a 30-60-90 degree right triangle.
\n" ); document.write( "-----
\n" ); document.write( "Let the side opposite the 30 degree angle be 1
\n" ); document.write( "Then the hypotenuse is 2
\n" ); document.write( "And the base is sqrt(3)
\n" ); document.write( "----
\n" ); document.write( "cos(30 degrees) = base/hypotenuse = sqrt(3)/2
\n" ); document.write( "==============================================
