What to do when majority of the students do not bother to do peer grading assignment? Thus, it is sufficient to state that the absolute error of the approximation 3.55 to the correct value 3.538385 is 0.012. You are providing only 2, x=.5, n=1 and x=1.5, n=2. Also, hand in any paper-and-pencil analysis you did for the exercises.

Close Tags for this Thread homework What are tags? Theory Absolute Error Given an approximation a of a correct value x, we define the absolute value of the difference between the two values to be the absolute error. If so, the plot generated is i43.tinypic.com/1628tb6.png Which shows both a blue line at the bottom and one going toward the top middle. –Khori Wood Oct 22 '13 at 21:44 Relative Error Function In Matlab The tutorial is here.

True Relative Error Formula

Sign in to make your opinion count. And, I believed that the adaptive step-size controller from ode45 was very good(?) –Sergio Haram Feb 19 '14 at 6:28 I have not tried to enlarge the integration interval How To Calculate Absolute Error In Matlab This does not mean that they that they actually use a fixed step size or that they use the step sizes specified in your TSPAN however. Maximum Absolute Error Matlab R=solve('(1/(18.99+273.15))-1.129241*10^(-3)=2.341077*10^(-4)*log(R)+8.775468*10^(-8)*(log(R))^(3)') %gercek R degeri Ri=3; tol=273.15+0.01; error=273.15+10 k=1; while error>=tol f=1.129241*10^(-3)+2.341077*10^(-4)*log(Ri)+8.775468*10^(-8)*(log(Ri))^(3)-(1/(18.99+273.15)); df=((2.341077*10^(-4))/(Ri))+(8.775468*10^(-8)*3*(log(Ri))^2)/Ri; Rnew=Ri-(f/df); fnew=1.129241*10^(-3)+2.341077*10^(-4)*log(Rnew)+8.775468*10^(-8)*(log(Rnew))^(3)-(1/(18.99+273.15)); error=abs(fnew) relativeerror=(error/R) Ri=Rnew k=k+1; end ezplot(relativeerror,k) Subject: relative error question From: dpb dpb (view profile) 5096 posts

The absolute error of the approximation 2.4 MV of an actual voltage of 2.573243 MV is 0.17 MV, whereas the absolute error of the approximation 2400000 V to an actual voltage Then, we get wild fluctuation until k = 16 or so, then a flat line.
