I know that I need to substitute and in and show they are the same but I'm not sure how to start and how to simplify

Thanks!

Start by doing the substituting and use 1/sine instead of cosecant. Remember that sin(x + pi) = -sin(x) because of how the sine wave works.

Not sure how that works with the /2 in there. So would I have

But I can't use there with it all being /2 can I?

Do x/2 = @ (theta) and use the formula they show at the link.

Sorry, but I'm not sure what you mean by

I'm really struggling with this and yet it seems like it is simple but I'm really missing the point I think.

What are you getting when you use the indicated substitution?
