The Attempt at a Solution

I have no idea where to start. I've been banging my head against this problem for 2 hours now. I just don't see how on Earth I can find theta with respect to x when it appears nowhere in the given equation! I think I am missing a key concept here. I don't want someone to just do the problem for me, but I need a starting direction.

Thanks!

Hi DanielFaraday! Welcome to PF!

I'm afraid it takes a long time to get an attachment approved (and a lot of members don't like opening them anyway).

Can you just type out the problem for us?

Wow. You mean to tell me that every single attachment is reviewed before others can view it? That's downright laughable. I hope whoever has that job is getting paid. Sorry, but that just doesn't make any sense. It creates a massive bottleneck that slows the entire forum down. What is the "Report" button for if not for reporting inappropriate attachments?

It also stops this foum being banned in schools/colleges/workplaces because someone posted porn, or a virus and it stops people leaving because every second post is an ad for viagra.

No, it only slows you down.

As I said, if you'd care to take the time to type out your problem, we'll take the time to help.

Now that the attachment has been approved ...

It looks like a typo. The first equation should be in terms of x and y, not y and z.

The description of each aperture (single slit, or rectangular aperture) is really telling you about the limits of integration.
