I tried approaching it from the equation $ n=\frac{sin(\frac{A+D}{2})}{sin(A/2)} $$ n=\frac{\sin(\frac{A+D}{2})}{\sin(A/2)} $ I got to this equation $ n= cos(D/2)+ cot(A/2)sin(D/2) $$ n= \cos(D/2)+ \cot(A/2)\sin(D/2) $ and i tried to see how D(minimum deviation) changes with A(prism angle) but i couldn't figure it that way.

I did have a simple thought experiment were if i decrease the prism angle to a point where the prism angle is close to 0° the minimum deviation would be close to 0° too. So i have a feeling that the minimum deviation would increase as the prism angle increases. I'm not sure if I'm correct on that please help me clarify it

I did have a simple thought experiment were if i decrease the prism angle to a point where the prism angle is close to 0° the minimum deviation would be close to 00° too. So i have a feeling that the minimum deviation would increase as the prism angle increases. I'm not sure if I'm correct on that please help me clarify it

How does the minimum deviation change with the prism angle?
