I'm sorry, could you please explain number three more in depth? I'm still confused about it.

I have a question with three problems please, if anyone wouldn't mind. A detailed response would be preferred if you have time, since I'd like to understand it instead of just getting an answer. Thank you for any help, it is greatly appreciated!
1. Give exact answer in radians.
2. Solve the following equation for
3. Find all values of x

Alternate interior angles between two parallel lines intersected by a transversal will be equal to each other. Since the two lines AB and CD do not have alternate interior angles equal to each other, they are not parallel.

Here's the video that I watched when I was first learning how to solve it:

This is a slower method, but it's a good way to start and just learn some basic algorithms. I can now solve it a lot faster and use short-cuts.

I found this forum while searching for some help in my current trigonmetry class, and I was surprised by how friendly and helpful the community was, so of course I instantly wanted to be a part of it. My name's Rachel, I'm particularly into biology, but I love math too. I've always been especially good at algebra, geometry, and precalculus... but now that I'm taking trig, I find that I'm really struggling with memorizing all of the assorted formulas. And that's pretty much my math history in short. Anyway, hello to you all!

Thanks so much, Daniel!
#12 Re: Help Me ! » Really confusing... » 2008-04-09 08:12:19
Sorry, my bad, I messed up the first part. It's supposed to be sin + csc (not sin + cos), but the rest is correct. Any ideas?

This question just confuses me, I'm not sure what it's getting at...
If
find the value of:
Is it just four? I know 1/sin is csc, and 1/csc is sin... so I feel like it's just the same question. Maybe I'm just not understaning if there's something more to it. Help please?

In
ABC below, tan(<CAB)= and the altitude from vertex A divides BC into segments of length 3 and 17. Find the area of ABC.
I've been working on it, but I keep getting stuck or lost.

Wow, thank you guys!
You both explained it differently, but I think it actually helped me understand it a lot better. Thank you.
