Finding Square Roots w/ Recursion

I'm trying to write a method that finds the square root of a number using recursion. So far i have the following:

publicdouble rootMeth(double a)

{

if (a < = 1)

return a;

else

return a / rootMeth(a-2);

}

I know this is not right, but it does work for a few numbers, if you can help it would be appreciated greatly. Thanks.
