The names of several equations

[Pual Black]

i have this 4 equations but don't know there names. I found them in a paper but without any information.
the equations are

1--$R.P=\frac{8}{\Theta}$

2--$D=f\sqrt{8(1-\frac{m\lambda}{2nd})}$

3--$V=\frac{2R}{1+R^{2}}$

4--$I_{sp}=\frac{8}{\pi^{2}}I_o$

i would be grateful is someone can tell me their names ( if you remember them )

Do you think that every equation have a name?
Very few do and the name is not really relevant for the understanding.
It does not matter what you call them. You should try to understand what they mean.

Well it would help a lot if we could see the paper. Is it available via an on-line link? Is it copyrighted?

And as already said, they may not have names per se.

yes you are right but i thought every equation should have a name. Look like i was wrong.
anyway these equation are from a paper about optics.
i wanted there names so i can derive them and use them in a better way if i know where they come from. Yes i will get them in the next weeks from the prof. but i thought it would be a good idea to look them from now and be prepared for them.
i tried to write these equations in google but with no results.

It's not the name that will help you to derive them. The first thing to know is the significance of each symbol in the equation.
Any serious paper or book will give the meaning of the symbols right after the first time they show up. Unless there is a table with all the symbols at the end or beginning (for books).
