Ran in:
syms r
psi_list = [1, 0.1, 0.01, 0.001]; % example: 0.1, 0.01, 0.001
figure
hold on
for i = 1:numel(psi_list)
psi = psi_list(i);
alpha = (12*psi)^(1/3);
l1 = @(r) (r + alpha)*(r + alpha);
l1a = @(r) r*r - r*alpha + alpha*alpha;
L1 = @(r) log(l1(r)/l1a(r));
t1 =@(r) (2*r - alpha) / (alpha*sqrt(3));
T1 =@(r) atan(t1(r));
l2 =@(r) (1 + alpha)*(1 + alpha);
l2a =@(r) (1*1) - (1*alpha) + (alpha*alpha);

W3 =@(r) 4*(T1(r) -T2(r))*(T1(r) -T2(r));
W4 =@(r) (L1(r) - L2(r)) + 2 * sqrt(3) * (T1(r) - T2(r));
W5 =@(r) 3 ./ ((r - 1) * (r - 1));
W =@(r) ((W1(r) + W2(r) -W3(r)) * W5(r))/W4(r);
