There is also if I remember a slight difference between the secant method and regula falsi.

The second one is slightly off.

No matter how it is phrased it is not my favorite choice for obtaining roots.

]]>This time, I came up with another confusion on the subject. Just over-viewing the subject, I found two entirely different (apparently, at least) formulae for the method. One is:

x1 = [a * f(b) - b*f(a)] / [f(b) - f(a)]; where a and b are two guess points.

The other is:

x = [xn - x(n-1)] / [f((xn) - f(xn-1)] * f(xn)

Are these two formulae actually the same or different for their use in different situations. Please help keeping in mind that I am just a toddler in this branch of mathematics.

I hope and wish * bobbym *is somewhere around.

Thanks in anticipation.
