This is an assignment I'm having trouble with, it's due next class (Tuesday). I've answered some of them so I'll just post what I haven't. Trig is really hurting my grade and frankly I don't care if I learn it as long as I get out of this unit (which seems to have gone on forever) with a passing grade.

Verify each identity

Solve each equation over the interval [0,2pi]. Give exact answers (I guess that means radian form.)

Find the complete solution set for each equation. Give exact answers.

It's been a while since trig, but I can say this:
tan2x - 3 = 0
tan2x = 3
tanx = sqrt(3)
x = tan-1(sqrt[3])
x = pi/6, 5pi/6, 7pi/6, 11pi/6

Do you still need these?

Do you still need these?
Yes. I actually have an AP exam tomorrow and don't have to turn these in until Thursday now. (We are excused from all classes for the day if we have exams.)

Ok, I tried to show all my work. I'm just hoping it makes sense to you.

All wrong. Terribly, disgustingly wrong.
You get an F.

Not really sure how to do:
(http://sidoh.dark-wire.net/upload/viewitem.php?id=126)
but those are the answers. I'd probably say guess and check with each value you have on the unit circle.
Or... you could graph it and look at the graph.

Alright, I hate to be a nuisance but had you intended on doing the other 4 or so? I just need to know since I have to turn this in 11 hours from now.

yeah, let me type them up

I think that's it. Sorry about no work, calculators have made me lazy.
