    Fixed-point iteration method to find an approximation

    the equation will get a result out of the range [2-3] ----- another question how can i know the number of iteration in fixed point , if I'm given the g(x) equation and error occur withing 10^-5 ex: x=((e^x)/3)^(1/2) within 10^-5 I'm not given the range of the period.

    Fixed-point iteration method to find an approximation

    yeah i know this equation but this is the answer in the solution manual also what's the equation for knowing the number of iteration in fixed point? i know this equation (k^n)/(1-k) [b-a] <error is there an easier form ?

    Fixed-point iteration method to find an approximation

    then the 2nd condition "2. max and min value of the function is between [a,b] which in this case is 2,3" doesn't meet with this equation. i've tried to get the solution from fixed point iteration calculator http://maccery.com/maths/fixed_point.php x=(25)^(1/3) Accuracy = 10^-4 Starting...

    Fixed-point iteration method to find an approximation

    there are 3 rules that every equation must pass before making iterations 1. function is continuous 2. max and min value of the function is between [a,b] which in this case is 2,3 3. [g'(x)]<1 so when i put 2 it should be within 2-3 range same for 3... but when i add 2 it gives answer out of...

    Fixed-point iteration method to find an approximation

    1st condition of fixed point iteration solutions must be within the range [2-3] it's very similar to Newton but i must use it to get the roots i've checked wikipedia but still i can't figure out what's wrong , I've checked the solution manual of numerical analysis burdon , they got the...

    Problem with Laplace transform unit step function questions

    so the answer i added for the problem is right? also is there a reference with examples? i get confused when solving problems like l{u(t-pi)sin2t)

    Problem with Laplace transform unit step function questions

    in this step L{2(t+1)}=2/s^2+2/s i expanded the equation to (2t+2) then used Laplace transform for t^n & constant , is this right or wrong , since i understand that U(t-1) is the shift of the equation

    Problem with Laplace transform unit step function questions

    is there a good reference with examples , i need to understand this part a little more. the (t-a) is the shift , so i shouldn't be expanding it in the problem i solved above !
