Square-Root by Newton-Raphson method.

Visualization of the process getting Square-Root by the Newton-Raphson algorithm. (9 iterations) Slide "S" to select the number that you want to get the square-root of. Slide "x0" to select the initial guess. "sqrt(S)" shows the x9, i.e., the 9th iteration of guess. "error" is the difference between x9 and computed value of sqrt(S).
