printing succsessive values

Hi I am fairly new to matlab and i have been given some questions. I have done questions 1,2 and 3 but cannot work out question 4. Any help would be much appreciated, sorry if iv been a bit vague.

1. Rearrange the equation to make the subject f:

2. Create a function segment(A,r) to find the arc subtended for a given area, and radius.

3. Make sure your working directory is in the Matlab path, and then solve for phi for Area of 0.1 m2, and a radius of 0.3 m.

4. Make your program print out the successive values of phi.

function phi = fragment(A,r)

% fragment the angle subtended by a circular segment

% fragment(A,r) is the fragment having an area A, and radius r.

% area of segment A = r^2 * (phi – sin(phi))/2

phi1 = 2*A/r^2;

phi2=phi1;

phi = sin(phi2) + phi1;

while abs(phi - phi2) > 0.0001

phi2=phi;

phi = sin(phi2) + phi1;

end

Many thanks Si

Remove the semicolons from the end of the two assignments to phi
