I am literally at a breaking point. I fractured my femur like 9 weeks ago so was our for Cross Country Season for College. I run cross country, track and field. Over the summer I was 105 pounds, since my injury I am up to 119. I really only took 5 days off in the beginning and went right into the pool, elliptical, and now run up to 5-8 miles on the tredmill. I eat really healthy. My weight just keeps fluctuating like crazy. Last week I was down to 111 and in a week that passed I was up to 120. I am doing so much and trying so hard to lose weight. I have no idea how to and why nothing is not working. I only eat like 1200 calories or so. It's terrible. What can I do? Why is this happening? My thigh muscles are huge. I have bigger breasts than ever. My arms are blowing up and my legs have stretch marks everywhere. It makes no sense. My clothes don't fit, and I do not feel myself when I run.

HELP

Compute the line integral of the vector field <7y,-7x> over the circle x^2+y^2=16 oriented clockwise

I keep getting 0 but it says it is incorrect

Integrate x^2+y^2 by switching to polar coordinates.

The original bounds are o<y<Sqrt(16-x^2) and -2<x<4

I know that I need to switch to polar so it becomes r^2*r(drdTheta) but I don't know what my bounds would be...

HELP

Use the Chain Rule to calculate the partial derivatives:

g(x,y) = cos (x^2+y^2)

x= -(4u+v)

y= -(u+v)

Definie in terms of the independent variables!

Hi, I am a cross country runner for my college cross country team. I eat really healthy every day. I exercise like a maniac as well. Over the past month and a half, I've put on 12 pounds. I'm super depressed about this. I'm only 5'1.5 inches and none of my clothes fit right now. I am not eating any more that usual. I've been taking prozac since february, could it be the result of this? I use to suffer from an eating disorder. I went from 104 to 116 in a month and I don't know what else I can do to lose this weight. I want to get off the prozac since it helped me get over my eating disorder and am no longer depressed/ have a better relationship with food. I need to lose this weight!

So for a while now I have been running four miles a day and counting all the calories that I burn at the gym out of fear of gaining weight. I feel as if this is all mental. I want to reduce my cardio down to the eliptical for an hour and then running four miles and then another eliptical for ten minutes. This would reduce my calories burned down to 1300 instead of 1600. I eat really healthy and have lost a lot of weight but now I want to maintain. Will I gain weight from this reduction if I keep my diet clean?

Ive lost 40 pounds over the past year and am very active. I ran cross country and track and work out a lot. I still work out for two hours plus a day. I run a lot as well. In the spring I was regular and would be able to go to the bathroom every day before track. There was a time that I had not gone for a week and took a laxative. I took them like three times because of this problem. I didn't want to be addicted so threw them out. All summer i go through periods of not going for a week and then going a little bit. It makes me gain like 5 pounds on the scale which gets me so upset. How do I get regular again?!

I'm 18 years old and over the past year I've dropped from 145 to 105 or less on a given day. I'm perfectly happy with what I weigh now and just want to maintain this weight. I work out every day for like two hours or so. I run every day and ran cross country and track this year. However I have not gotten my period since march and am concerned. It's been irregular all year and I want to get it back because I am worried. What do I do?

I use to take days off when i first began to lose weight but I did cross country and track and then would go to the gym after. I use to only run 2 miles a day and now I'm not satisfied with anything less than 4 plus I go to the gym and burn 800 on an elliptical, 100 on another, then 164 on the stair machine. I want to go back to only workin out 2 hours a day but I am afraid of gaining weight. What do I do?

I've lost 40 pounds since last summer but this yea I've gained this addiction to workin out and being skinny. Every day I work out three hours. I go for hour long runs then go to the gym for two hours and do the elliptical for an hour and ten minutes and another elliptical and the stair masters. I literally do this every day and am terrified to stop. I didn't work out today for the first time and I am freaking out. I am going away to school in the fall, how do I. It gain weight?

I want honest answers, college help!?

What do you think my chances are of getting into some of these schools given this information: 1870 on SATS (so bad I know), ranked 4 out of 200...gpa of 4.0 on 4.0 scale, I'm involved with so much, cheerleading, cross country, student council, key club, business club, academic team, youth group, peer leadership, I volunteer at a nursing home, and I work. I know the girls ranked one and two are applying to some of the same schools and have higher SAT scores, but individually how do I stand for Lehigh, Bucknell, Cornell, Boston College, Villanova, Penn, (a girl can dream), Lafayette

Please be honest!

My sat scores are really low. I got a 590 in math, a 620 in reading, and a 660 in writing. I have a gpa of 4.28 out of 4.3. I participate in cross country, cheerleading, softball, key club, student council, national honor society, spanish honor society, academic team, yearbook, business leaders, a church youth group, I work at a local store for most of high school, I also have tons of extra-curriculars and volunteered at a nursing home. What kind of schools should I be looking at? Is my SAT score going to bring me down? and I'm ranked 4th in my grade out of 160...What schools should I look at predominately on the east coast or so?

Around May my boyfriend and I didn't technically have sex. We were going to but I made him stop because I wasn't ready. He put it in me and I made him pull out. No thrusting or whatever. He had a condom on. I got my period for the next two months, but now I haven't gotten my period since the last time in July and that was the only time that I've ever done anything involving sex. I got my period the other day for a day and then a little spotting the next. I also work out like crazy and have lost 30 pounds since March. Am I pregnant? I'm going to take a test with my mom but I'm just nervous about that one time...

I recently lost like 30 pounds and work out like crazy. I also started cross country and run and work out everyday. I haven't gotten my period for the month of august. Is something wrong with me? And I'm a virgin, so no pregnancy. I have always been regular too so it's odd for me to be off since I've had my period for 5 years now.

Any advice? I'm 17 and have been with this boy for about a year. We always said we'd eventually do it. I've always been opposed because I felt my virginity was sacred. but recently I've actually wanted to do it. I want to be sure it's something that I won't regret. I am in love but I know how immature young love can be. I don't want to plan it but I want it to be special and I actually think I'm ready just because I'm so sexually bored with my partner. I'm tired of making out because it's all we do. Any advice? Is that a bad reason to do it?

I recently lost 30 pounds. I am so good with counting my calories and keep it under 800 a day. All of a sudden I am always hungry. I pick at everything. What is wrong with me? How do I make it stop? I don't want to gain weight back!

I'm 5'2 and about 126 pounds....I recently lost 17 pounds...I have worked out and dieted like crazy...almost too crazy. I have this obsession with not wanting to be fat and I fear for my life that I am going to gain my weight back again. I get scared to eat too much and hae developed this habbit of rubbing my arms and chin under my chin excessively to see if I'm fat...how do I stop this? Am I annorexic?

I had gotten really bad sunburn Sunday on my face where I had blisters in the middle of my forehead...They ended up popping and left me with chunks of dry skin that was peeling. Due to the hot weather, sweating, and working out, the skin ended up flaking off and now I'm left with a huge bright pink spot in my forhead...what do I do?

I am so frustrated. I've worked my butt off for years on hard work gettting nearly perfect grades. I'm ranked top four of my grade. I get impeccible report cards and never get b's, all a's but on my SAT I can't get past 1700 if I'm lucky. WHY AM I SO BAD? I've taken courses and worked hard and I still don't do good. I don't get it. HELP?
