Wikipedia says: If the initial values are not close enough to the root, then there is no guarantee that the secant method converges. There is no general definition of "close enough", but the criterion has to do with how "wiggly" the function is on the interval \$[x_0, x_1]\$. Secant method requires two initial values. Test shows that this method converge a little bit slower than the Newton-Ralphson method. Numerical Searching Methods Start & Purchase <More Open Source & Learning Here> Special!
