We want to prove that\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " (where cos theta is not equal to 1)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This is true if and only if\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " (multiplying both sides by 1 - cos(theta)).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ", adding cos^2 (theta) to both sides yields the Pythagorean identity. Hence the original statement is true.
\n" ); document.write( "
\n" );
