Head phone requirements:

-wireless (no wires please)

-comfortable (good for long sittings of use without irritating ears or head)

-durable (can lay in bed with and maybe even lay on my side without breaking them)

-good quality microphone (internal or external mic)

-good quality sound (crystal clear)

-Affordable ($0-$150 it would be nice if it was on amazon)

I found these: They seemed perfect. However, I read some comments and I heard that the internal microphone isn't that great. I would like to talk to friends, with a good mic, when on skype or playing dota 2.

Please help I cant remember the name of the anime and i have been searching through my history with no luck.

I think there was light colors and the ending song was centered on a girl that wakes up and drags herself to school and is boredly going through the school day. Near the end of the song a huge tree sprouts and grows around her (i think in the classroom) and the singer sings really fast i think the last lyric was "hundee" the singer was singing in Japanese and that's not even a Japanese word i watched it subbed i think the song was about her saying she doesn't want to go to school or she doesn't want to wake up or something. The art for the ending song i think didn't have a recognizable character in it and the art i don't think wasn't matching the same drawings of the show.

I had an argument and I do not believe that I am wrong. Should I apologize? Do you not have to feel apologetic for it to be an apology? Wouldn't it be a lie/deceiving if I didn't mean it? That would contradict the meaning of an apology?<--- MY THOUGHTS. WHAT'S YOURS?

A similar problem on yahoo answers helped me on a problem http://answers.yahoo.com/question/index?qid=201109... this problem is in the same category but different. Please help and explain.

A ball is dropped from the height of 9ft. The elasticity of the ball is such that it always bounces up one third the distance it has fallen.

(a) Find the total distance the ball has traveled at the instant it hits the ground the fifth time.

(b) Find a formula for the total distance the ball has traveled at the instant it hits the ground the nth time.

I already tried the problem and for (a) i got a mixed fraction 17 and (25/27)ft. the book says the answer is 17 and (8/9) (im off by about 0.1)

for (b) the answer is 18-(1/3)^n-3 but i don't see how it works and how they got it. Some one please explain!

math help how to change θ=(-π/2) to rectangular coordinates

the answer in the back of the book is x=0... and on the unit circle negative pi/2 is at the same spot as 3 pi/2 and the x and y are (0,-1) but in the back of the book and in other problems the answer is always x=(number) I do not understand why y=-1 is not listed. If possible I would like a solution with detailed steps for why θ=(-π/2) equals x=0.
