Here's what I need to do: "Compare the effectiveness of the bisection method and Newton’s method for the equation x^3−2x−2 = 0 which has a single root between x=−4 and x = 2." So far I've done ok. this is working but of course I need to do iteration which I don't know how. Can someone teach me please? I'm trying the Newton-Raphson Method first. Thanks for the help in advance. EDITED: Sorry, I posted the wrong pic earlier. Here's the correct one.
