I see, now I can derive the equation. Thank you so much for your help!

sorry for the unclearness of the picture, my cellphone camera is very crappy.

I appreciate your patience, but sorry, I can't see the other similar triangle that can help. On the other hand, the relation ΔAOF≈ΔGMF only gives you AO/GM=MF/OF which is h/GM=(f+o)/f in this case i think we cannot assume GM=h' because if you draw a bigger diagram you can see that GM is...

Yes, I drew a diagram just like you described, and I did find a similar triangle of AOF and GMF, but pardon my slowness in math; I failed to see how the rest of the derivation goes. So can you please elaborate on the rest of the similar triangles and how the final result is derived?

Yes, but where are the similar triangles, and how do you proof them?

Hello everyone, I really run into a problem here. The magnification equation for mirrors describes such a relation: M=-distance of image/distance of object = height of image/height of object. (M=(-i/o)=h'/h). I understand how this formula can be proved using a ray diagram for concave...
