Hi, hope that someone can help me on this. I want to plot a graph of this equation:
I have fix value of B,w and d. x-axis will be inner angle and y-axis will be outer angle.
Thank you in advance for any assistance provided.

You can try meshgrid and contour

There is a missing pair of parentheses (corrected here):
f = @(ii,o)1100/100+sqrt((1100/100-2*sind(19.42)).^2-(cosd(19.42-o)-cosd(19.42+ii)).^2)-(sind(19.42+ii)+sind(19.42-o));
however if you plot the function, it never equals 0 in the desired range (or anywhere else):
[X,Y] = ndgrid(-500:10:500);
figure
surf(X,Y,f(X,Y))
so fimplicit will fail.

The function won't become equal to zero in your case. meshgrid might work and generate the required results.
