Secant Method

What is a Secant Method? The tangent line to the curve of y = f(x) with the point of tangency (x0, f(x0) was used in Newton's approach. The graph of the tangent line about x = α is essentially the same as the graph of y = f(x) when x0 ≈ α. The root of the tangent line was used to approximate α.
