MATLAB: Help me to make a function of while loop

homeworkno attemptwhile loop

How to use while loop to numerically sum the infinite series given as

(1/1^4)-(1/2^4)+(1/3^4)-(1/4^4)+(...)

and the program should stop when the last term becomes smaller than 0.0001

please somebody help me, I'm desperate to make this project all of my friends doesn't know how to solve this problem and i have no one to ask for..

Best Answer

ii=1;
A(1,1)=1/(1^4);
while abs(A(ii,1))>=0.0001
    A(ii+1,1)=((-1)^(ii))*(1/((ii+1)^4));
    ii=ii+1;
end
RequiredSum=sum(A)

Put

xi = 0;
xf = pi; % or whatever your desired start and end values are.
f = NumIntf(xi,xf)

in a script and run that - it worked for me.

I felt a bit bored so I do the coding for you. Also I might have use for this in near future. Just run arcCosSin in command window.

Next time try a bit harder to do the homework yourself. You could get a lot of Matlab programming tips through Google.

function [] = arcCosSin()
  % Written by GLO on 11.Oct.2011
inputnum = input('Please Enter a number between -1 and 1 for the arcCos and arcSin: ');
if (inputnum<-1 || inputnum>1)
    fprintf('\nThis program only gives the answer for input between -1 and 1\n');
else
    sinDeg = asind(inputnum);
    sinRad = asin(inputnum);
      cosDeg = acosd(inputnum);
      cosRad = acos(inputnum);
      fprintf('ArcSin in Degree is: %0.2f\n',sinDeg);
      fprintf('ArcSin in Radian is: %0.5f\n',sinRad);
      fprintf('ArcCos in Degree is: %0.2f\n',cosDeg);
      fprintf('ArcCos in Radian is: %0.5f\n',cosRad);
  end
