1.9.4 Newton-Raphson method (A-level only)

Card 1 of 24

Graphically, where is a root of f(x)=0f(x)=0f(x)=0 found?

A

At an xxx-coordinate where y=f(x)y=f(x)y=f(x) crosses or touches the xxx-axis.

B

The formula requires division by zero.

C

If f′(xn)f'(x_n)f′(xn​) is very close to zero, the tangent may intercept the xxx-axis far away. A poor starting value may lead to a different root.

D

x1≈1.347826087x_1\approx1.347826087x1​≈1.347826087.
