#94154 - square root by Newton's Rule
Responding to: ???'s previous message
Hi Again Neil,

Here's one I dug out of a book.

U_(i+1) = 0.5*U_i*[3 - V*(Ui^2)]

U converges quadratically to the 1 over the square root of V. Or, multiply it by V and it will converge to the square root of V.

Obviously you will need an initial guess for U_1.

I hope this helps.
