I am getting problem in answer please help me to find it.
function mbd= spherical_mirror_aberr(fn,D)
format long
f= fn.*D;
Delta_x= 0.01;
x= 0:Delta_x:D/2;
theta= asin(x/2.*f);
d= 2.*f.*tan(2.*theta).*((1./cos(theta))-1);
mbd= (((8.*Delta_x)/D^2).* sum(x(:).*d(:)));
end
ans for (8,152) is 0.029743954651679 but i am not getting this.
