Numerical Methods

• If there is a change in sign and the function is continuous over the interval it shows there's a root
• To determine convergence start with the iterative formula and draw to the line $y=$$x$
• A staircase diagram converging

  
• A staircase diagram diverging

  
• Cobweb diagrams can both diverge and converge
• Staircase diagrams can both diverge and converge
