You can put this solution on YOUR website!
$\"a+=+1%2Fsqrt%281-B%5E2%29\"$ \r
\n" ); document.write( "\n" ); document.write( "I personally would rewrite in terms of powers:\r
\n" ); document.write( "\n" ); document.write( " $\"a+=+%281-B%5E2%29%5E%28-1%2F2%29\"$ 1/2 means the square root (1-B^2) and the negative sign means to take the reciprocal of this result ie one divided by the result.\r
\n" ); document.write( "\n" ); document.write( " $\"a%5E-2+=+1-B%5E2\"$ raise both sides to the exponent -2. Remember that when you raise a power to a power you multiply them together so -1/2 * -2 = 1\r
\n" ); document.write( "\n" ); document.write( " $\"1-a%5E%28-2%29+=+B%5E2\"$ take one from both sides and multiply by -1\r
\n" ); document.write( "\n" ); document.write( " $\"%281-a%5E%28-2%29%29%5E%281%2F2%29+=+B\"$ raise both sides to the power of 1/2\r
