Use Benchmark:

cmpthese -1, { 
    a=>q[
        $sine = rand( 2 ) - 1;
        $cosine = sqrt( 1 - $sine**2 );
    ],
    b=>q[
        $angle = rand( 2 *3.14159 );
        $sine = sin( $angle );
        $cosine = cos( $angle );
    ], 
};;
       Rate    a    b
a 1614300/s   -- -28%
b 2246655/s  39%   --
