Draw a right triangle with acute angles of 30 degrees and 60 degrees.
\n" ); document.write( "Let the side opposite the 30 degree angle have length \"1\"
\n" ); document.write( "Then the hypotenuse will have a length of \"2\".
\n" ); document.write( "Then, using Pythagoras, the third side will be sqrt 3\r
\n" ); document.write( "\n" ); document.write( "The Cosine of an angle is (adjacent)/(hypotenuse)
\n" ); document.write( "The side adjacent to the 60 degree angle is \"1\".
\n" ); document.write( "So the Cos 60 degrees is 1/2
