• ### Solving equation for z raised to fractional powers?

(4/3) * R * z^(3/2) - (2/5) * z^(5/2) = (-sqrt(2g)*s*t/pi + C)^2 z is the variable I am solving for and z is a function of t. All other variables are constants. So basically I need a z on one side of the equation and everything else on the other.

• ### Boyfriend doesn't say "I love you" anymore unless I say it first?

My boyfriend and I have been going out for a little over 6 months now. He used to say "I love you" before I would say it but now hasn't for a few weeks unless I say it first. He will always say it back if I say it first but it worries me that he hasn't said it first in a while. He has been extremely busy and tired lately so... show more

• ### Boyfriend going to different college?

My boyfriend is graduating from our college in June and he originally told me he'd be staying here for grad school. However, now he's changed his mind and is going somewhere about 40 minutes away.

My boyfriend is graduating from our college in June and he originally told me he'd be staying here for grad school. However, now he's changed his mind and is going somewhere about 40 minutes away. I'm freaking out because I can't stand being apart from him. He was gone visiting the other college for 2 days and it about killed me. I don't have a car so the only way I can see him is if he drives to pick me up so I doubt he'd be able to do that except on weekends and even then probably not every weekend. I really want to be happy for him but this is tearing me up inside. I know it's only 40 minutes away (or 3 hours on the bus if he can’t pick me up) and could be WAY worse, but after thinking for months that he was going to stay here it's quite a shock and I just don't know how to handle this. I don't know how to talk about this with him without seeming clingy (which I'm terrified of) or ruining his excitement and happiness which I would like to be able to enjoy with him. What should I do to make myself feel better and stop the worrying? I'm seriously losing sleep over this. We've only been going out for 3 months so far but I definitely trust him and we’re not going to end things. Please help and please no negative comments about how it could be worse, etc. Thanks so much!

It could also be that I'm pretty shy and have a difficult time letting my guard down...could it just be that I'm afraid to get close to someone like that? Please help! I just wish this horrible feeling would go away so I could enjoy this stage of potentially being in a relationship instead of feeling nauseous. (I'm 18 by the way and have had one boyfriend before if that makes any difference. That relationship did have a difficult breakup, but I had this feeling before that relationship too.)

I think it may just be that even though I really want to be in a relationship it's out of my comfort zone and I'm not good at letting my guard down. Any ideas how I can get the extreme nerves to go away?

He likes to hug me a lot and we sit close together when watching tv and sometimes he leans on me. He also likes to compliment me on what I'm wearing/my jewelry and things like that. However, he says I'm like his "big sister" (maybe this is the answer right here?) but in a funny voice, so is he just joking? He also likes to poke me a lot and likes saying my name. We just got back to college after winter break a few days ago and when I told him some of our other friends (but not me) were going out to lunch he said "are you going?" and I said that I wasn't and then he sounded sad. Also when we first got back he hugged me (squeezing the breath out of me lol) and said really quietly "I missed you!". So do you think we're just really good friends or might there possibly be something else there?
