I tried dividing through by s. So we get

in x + in x * co x = 4/s

now multiply by both sides by the inverse of in x which is out x

1 + co x = 4 * out x / s

which leads to

co x = 4*out x / s - 1

co x = (out x +out x +out x +out x )/s - 1

co x = ( rfo x) / s - 1 (rfo = really far out)

now divide thur by o

cx = rfx/s - 1/o

cx = (rfxo - s) / so



take first derivitive

cso = rfo

such forth cs = rf

now factor into the mother equation....
cx = (rfxo - s) / so
which leads to
rfx= (rfxo-s)/o

what should i do from here? thank you fellow answerians :)

Would it be any easier to find "ghosts" in warmer temperatures or cooler temperatures? Or does it not matter at all.

I know that in a LONG time that the Milky way galaxy and the Andromeda galaxy will collide.But whats the worst that can happen? It just stars crashing on stars (yes that can be BAD) but aren't we far away from stars (other than the sun) But Will mankind survive this collision?

I mean, when something happens out of the ordinary (and what are the odds), skeptics will shrug it off and say "Oh what a coincedince" and never attribute the incident to spirit? why?

I was thinking the other day about how much obesity there is in the US and stuff and this random thought occured to me:
If people continue eating so much junk food, would it be possible that someday we could evolve so that our bodies would be better adapted for this kind of food and it would actually be GOOD for us?

I really know pretty much nothing about evolution, could you help me out?

Say this year you find out that your dad's best friend died in a fire in 1983. Soon, time travel is discovered. If you go to 1983 and save your dad's friend, wouldn't a paradox result? If you save him in 1983, the future you had no reason to go back to 1983 in the first place. Right? Plus, what would happen to everyone in the future who knew the guy died? Would he suddenly materialize? Doesn't time travel sound impossible because of these problems?

Jupiter, Saturn, yada. This seems to be the stuff of stars. Now I am no physics or mathematical student (let alone a genius). They sound to me like failed stars. Let's assume they are. My question is this, "Would it still be possible for them to 'ignite?'"

I just had a neuropsychological eval for possible brain damage. I've never had a test like that that took 5 hours. I started getting a headache during the spatial testing. Then I started getting dizzy and felt weird and spacey the rest of the day. Is this normal? Why did I feel this way after the test? I normal don't feel weird like that.

On the way home I felt really spacey and next thing I know I am falling up the steps. What did those tests do to my brain??

Please only answer if you are a medical specialist or an experienced patient. Thanks.

I know the sun has strong gravity.But If our sun pulled our planet from some other place and pulled us this close why doesn't it keep on pulling us into it? Basically why doesn't the suns gravity(pull) suck us in the sun itself?

...what is the length of the resulting crease in terms of x and y? I figured it out once, but can't remember how I did it. My equation, however, needed x to be the shorter side and y to be the longer.
