Question

Can someone help explain "Newton's method"?

Answer 1

it is method for finding approximately solution of equation
f(x)=0. You pick some starting point and then you compute tangent line to the f(x) in this point. Then you repeat these steps, but now picking point where tangent line=0 (crossed x-axis) as your starting point.

thanks

Answer 4

It is very fast approximation method, but be careful. It can easily fail to find the solution.
