Hello,

Firstly, I'm not sure if this is the right area to be posting this but someone referred me to this forum for help with this proof. I am not very good at proofs and I think the one I need help with is pretty simple but I could be wrong.

Here are the instructions given to me:
For the argument below, you are given three premises and a conclusion. Construct a formal proof.
1. Small(a) ∨ Medium(b) ;Premise
2. Larger(c, b) ;Premise
3. c = d ;Premise
4. Large(d) ;Conclusion

Attached is a screenshot of the tiny start that I have to this proof. Any help would be very much appreciated!
