First of all, I don't care if anybody chooses my answer because I tend to delete mine when I rethink that I maybe I don't really have a good answer for that question and I'd really wish somebody else would give a better answer. I don't care about points but I do care whether I am honest and don't try to screw anybody else's life with thoughtless answers. I don't make a joke out of this because lots of times I wish to get answers for difficult questions and I don't have any expert friends to help me like some users do and think they are somehow too good to need any real advice off the Internet. I am sick of those who use this forum for kicks and don't care how they really hurt people. If you don't understand, then don't be mean by answering how you'd never trust what is on this site. I am not saying I trust everything on this site but I feel better to get some different thoughtful serious answers. There's enough garbage in life and those jerks just make me more cynical.

1 AnswerHistory8 years agoWhat is the derivative of of y = 1/(2x)?
I get dy/dx = -1/(2x^2)...But I'm not sure that is correct. Is there is suppose to be a minus sign?
Also please show me in steps...how to do this properly.
Thanks.

3 AnswersMathematics1 decade agoHow do i reduced this to get the O() time?
I don't have the summation symbol
T(n) = 2T(n-1) + O(1)
a= 2, b =1, f(n) = 1
T(n) = Summation from i=0 to i= log(base 1) n (2^i)*f(n/1^i)
T(n) = Summation from i=0 to i= log(base 1) n (2^i)*n/1^i)
T(n) = n * (Summation from i=0 to i= log(base 1) (2^i/1^i)) ;factor out n
T(n) = n * (Summation from i=0 to i=log (base 1) (2/1)^i)
T(n) = n* [2^(log(base 1)n +1) -1]
How can i reduce it further? Can you explain?
1 AnswerMathematics1 decade agoWhat is 8^i/(2^i*2^i)?
I think it is:
=8^i/2^(2i)
=8^i/4i
=?
Please explain.
Thanks.

Please explain so i can understand why.
3 AnswersMathematics1 decade agoCan some explain how this summation with power i should work?
There's no summation symbol so i have to use words.
(Summation from i=0 to log(base 2)n ( 4^i c*n/2^i))
So then i take cn to the outside of the summation...
cn (Summation from i=0 to log(base 2)n 4^i/2^i)
I am wondering can I put I make:
4^i/2^i = 2^i
that is within the summation
Or would that be wrong?
1 AnswerMathematics1 decade agoHow to reduce this logarithm problem?
I copied what was on the teacher's notes but now that I look at it, I'm confused.
The first line he wrote was:
((cn)/3)logn - ((cn)/3)log3 + ((c2n)/3) + ((c2n)/3)(log2n - log3) + n <= cnlogn
I am confused how he got to the next line which I am stuck on:
((cn)/3)logn + ((c2n)/3)logn - ((cn)/3)log3 + (c2n)/3 - ((c2n)/3)log3 + n <= cnlogn
-(cn)log3 +(c2n)/3 + n <= 0 Since n cannot equal 0, we can can forget about n.
-clog3 + (2c)/3 + 1 <= 0
1 <= c(log3 - 2/3)
1/((log3-(2/3) <= C
Can someone explain to me in full detail how he got to the second line, then the rest. I understand the log rules but I might be missing something in between. The teacher goes very fast.
I appreciate your help.

Are there any librarians out there who would know where i can get this information?

2 AnswersMathematics1 decade agoHow can I make my life more meaningful?
I am stuck at home because I haven't been able to get a job.
I would like to be able to make new friends but know really how.
I haven't seen any volunteer positions but I really need money because I have to take the bus.
I find days are painful.
I don't go to church and so it would be dishonest to go even if someone gave me money to take the bus.
I don't really have any interests. I tried many things but I don't like much things that don't cost money.

5 AnswersOther - Society & Culture1 decade agoHow do i get this guy to stop calling me?
He knows where i live so i am sort of afraid he'll get mad if i tell him to not to call anymore...He's very pushy...I hate pretending to be nice but he keeps calling. I just picked up again because i wasn't familiar with his cell phone. He was calling me at his home before several times. I don't want to see him either.
8 AnswersEtiquette1 decade agoWhat should I do about this guy i used to know?
I went out with him before he dumped me. Years later, now, he's called me saying his ex left him so he moved back into town. I have no feelings for him and told him so. I told him I was too busy to see him but he keeps calling me and wanting to have long talks. He wants to be friends and just hang out together because he's lonely.
As polite as I tried to be, I didn't really like rehashing the past. I don't want to be his friend. He had many friends but he lost touch with them when he got married. I didn't have any friends when he met me and so I was shy and insecure. I was heartbroken when he broke up with me but i am different person now and I feel disgusted by him for calling me now and wanting to see me.
On the one hand, I don't want to be known as the kind of person who cannot forgive and forget but then on the other hand, I don't particularly like to see or hear from him. Thinking about him annoys me and brings out all these bad thoughts like how he mistreated me.
3 AnswersPsychology1 decade agoHow do i tell a guy i used to know that i don't want to be his friend?
This guy i know and I used to go out together. But he dumped me. Several years later (now) he calls me and tells me his lady dumped him and he moved back into town. He just wants me hang out with him and just be friends because he's all alone.
I don't want to hang out with him because i have my own problems and i don't trust him to be a good friend. I'm no longer interested him but he's called me every day since he got back. I don't blame him for the past because I don't have any feelings towards him, anymore. I was young and stupid to be with him.
Now, I just find him annoying to want to have long talks with him when I'd rather concentrate on my problems. How do i be polite and tell him to go away?
I really don't like the way he thinks and I feel I know him too well to know what kind of character he is. I don't mind having guy friends but he's just not the kind of friend I can trust because he was dishonest with me.
I just don't want to waste my time with somebody like that
10 AnswersFriends1 decade agoHow do you cheer yourself up when you've been dumped?
My bf was my first interracial relationship and I believe he dumped me bc his folks didn't agree with us to being together. Everything between us were going wonderful until I met his parents who were not interested in getting to know me. He denies it had anything to do with his parents of course but he avoided me for weeks, ignored my messages, telling me he was busy at work. I finally caught him with his new girlfriend who happens to be white like him at a restaurant. That's when he had to tell me he fallen in love with someone else and that is over. He hoped that I could forgive him and told that we should keep our distance. He seems to be pushing me out of his life. He wants me to take a vacation or meet somebody else. He went from warm, loving, caring person to a totally different person who no longer cared about me or my feelings. He continues to avoid me, saying there was nothing more to say. He was busy at work.
