Given $$a>0,$$ we wish to calculate it reciprocal value $${1 \over a}$$ by using Newton - Raphson method for $$f(x)=0.$$ The Newton - Raphson algorithm for the function will be
A
$${X_{k + 1}} = {1 \over 2}\left( {{X_k} + {a \over {{X_k}}}} \right)$$
B
$${X_{k + 1}} = {X_k} + {a \over 2}X_k^2$$
C
$${X_{k + 1}} = 2{X_k} - aX_k^2$$
D
$${X_{k + 1}} = 2{X_k} - {a \over 2}X_k^2$$
