For example: a ) xex 1 = 0, b) 2 sin x x = 0 These equations can not be solved directly. Do you have PowerPoint slides to share? FIXED POINT ITERATION The idea of the xed point iteration methods is to rst reformulate a equation to an equivalent xed point problem: f(x) = 0 x = g(x) and then to use the iteration: with an initial guess x 0 chosen, compute a sequence x n+1 = g(x n); n 0 in the hope that x n! Rearrange the function so that x is on the left side of the equation:. If so, just upload it to PowerShow.com. FUN is a function handle.
