Sin is defined as opposite/hypotenuse.
\n" ); document.write( "Draw a right triangle with one point at the origin. Draw the hypotenuse (h) with an angle of 9 degrees above the x axis. The \"altitude\" gained is given by \"altitude+=+h%2Asin%289%29\"\r
\n" ); document.write( "\n" ); document.write( "At 2 miles, we have \"altitude+=+2%2Asin%289%29\" = 0.312 miles\r
