ERROR IN LINEAR INTERPOLATION

THE SECANT METHOD - University of Iowa

THE SECANT METHOD Newton’s method was based on using the line tangent to the curve of y = f(x), with the point of tangency (x 0;f(x 0)).When x 0 ˇ , the graph of the tangent line is approximately the same as the

The differential equations we consider in most of the book are of the form Y′(t) = f(t,Y(t)), where Y(t) is an unknown function that is being sought. The given function f(t,y) of two variables defines the differential equation, and exam ples are given in Chapter 1. This equation is called a first-order differential equation because it ...
