Given that SinA =1/8 , pi/2 <= A <= pi, find each

a) Cos2A

b) Cos A/2

Thanks a lot!

Find the exact value of Sin(1/2Arccos3/5)

Solve each equation for 0<=theta<2pi

1. sin( 2theta -pi/2) = -1/2

and

2. sqrt2 sin theta/2 -1 =0

thanks for your help!

1 +sec theta/ sec theta = sin^2 theta/1 - cos theta

AND

sin theta + sin 2 theta/ 1+ cos theta + cos 2theta = tan theta

thanks for your help!

The walking dead or Dexter? I have multiple seasons of each show at my disposal, and an afternoon with nothing to do! Which one do you think I should watch? I love them both.. So choose for me!

They're my favorite band, and I wanna know why you love their songs too! My favorite song is Andy You're a Star, cause it just OOZES sex appeal ;) What's your favorite? and please don't say anything like "Mr. Brightside, cause it plays on the radio a lot.."

Ok,what is the song that played while patrick dempsey, chelsea handler, and robert pattinson were being introduced to present reese witherspoon with the lifetime award? it was kind of a techno/indie sounding song, and i would really love to know the name of it! thanks

I'm just wondering. I've always thought it was a cool name, but would a girl get teased with a name like Andromeda? Maybe Andi for short? Opinions! :)

Just out of curiosity, what do you thing are some really good, sexy rock songs? Here are mine (so far).

Andy, you're a star - The Killers

D'yer Mak'er - Led Zeppelin

Addicted to you - Saving Abel

The Stroke - Billy Squier

Any good ideas? And please, no Marvin Gaye ;)

I'm going to see Muse at the John Paul Jones arena in Charlottesville on the 27th, and I just bought some tickets through a listing on craigslist. The person I bought them from doesn't really know if they're GA or not, but this is the info they gave me.. "The tickets say Row 3, Seats 39 and 40." (I don't think the tickets include a section number.)

Are they General Admission tickets?

All of my media is gone! Just today, I added some new music onto my ipod using the manually manage music and videos option. After that, I updated my ipod touch software, and unplugged it from the computer. For a while, it seemed like everything was fine, but then just a few minutes ago, I went to listen to ny new music and all of my 3,000+ songs and movies are gone! Now when I go to music, I immediately get a message that says "You must sync with your computer before you use music." My personal computer recently died after a nasty run-in with a power surge, and I am now using a borrowed computer (without all of my music on it). Is there any way to get my music back? Please help me.

I love cruisin', and I want to hear your best memory!

first of all, I love the Killers (and Brandon Flowers) and was really psyched to learn that he was coming out with a solo album! I just watched the new music video for "crossfire" and I was wondering whether or not it's supposed to be funny.. Charlize Theron plays the love interest to BF in the video, and she's beating up all sorts of ninjas and assassins. The video doesn't really fit the theme of the song, and I was wondering if you could help me..

Thanks!

OK, so I just looked on my requests on Facebook, and this guy I know pretty well, suggested a page to me called "will you be my girlfriend?"... It only has about 25 fans, and 2 of them are my friends.. Is he asking me to be his girlfriend?

Find an angle such that twice the supplement of the angle is 250 degrees more than the complement of the angle

Thanks a lot! :)

I'm rather interested in getting an Ipod touch, but im having a little trouble understanding the wifi on it.. Is the use of the wifi itself free? So if i find a free connection (That doesn't require a password) can i use the internet for free? My dads work provides wifi at our house so he can use his laptop here, so can i use his work signal at my house? Thanks :)

Eight Rubies, ten emeralds, and one hundred pearls which are in thy earring, my beloved, here purchased by me for thee at an equal amount, and the sum of the prices of the three gems were three less than half a hundred, tell me the price of each, auspicious woman.

Thanks :)

solve by factoring: x^2 = 13x = -42

x^2 + 16x = -64

l dont need the process, just the answer would be greatly appreciated. Thanks!

This October, my family and I are planning to go to Japan. What I'm wondering, is can you text to the United Sates from Japan? If i have unlimited texting, and my friends have unlimited texting, would it cause an extra fee on our bill to text them? Oh yeah, l have verizon.

Thanks!
