Helicoid

My front lawns been looking pretty bad recently, and it's gotten to the point where it's basically all weeds mixed in with a little bit of grass. I want to start fixing this, but I really have no idea what I'm doing. I did a little bit of googling and a lot of websites are telling me to basically kill everything and then plant new grass. Is there anyway I can avoid doing this? Thanks.

(x^2)y' +8xy -(3x^2)(y^2) =4

I know how to solve if it's in the form of y' +P(x)y = Q(x)y^n however that =4 is throwing me off big time.

Any help is appreciated. y' = dy/dx

y' = (xy' +y)y^2

i'm close to the form of bernoulli but not quite. It's been driving me crazy for a while now.

y' = dy/dx

This question is for anyone that believes in an afterlife. If you have a rock and crush it into a powder, that rock no longer exists. We don't believe that what that rock once was exists somewhere else eternally. If we build a machine that's capable of moving around, we don't believe after that machine is destroyed that it lives on elsewhere. Yet as humans a lot of us tend to believe that are thoughts, memories, emotions, personality may live on.

I argue that we're really just advanced machines capable of experiencing emotions. We can severely alter our consciousness and emotions through drugs. If someone is depressed, we can fix that through chemicals. If someone gets lobotomized or frontal lobe trauma their mental capacity and personality can be severely altered. We know that we can aim a magnetic beam to certain areas of the brain and severely affect a persons moral judgement. We know when areas of the brain responsible for certain abilities are destroyed, we know longer have that ability.

How can someone justify that are personality and memories are anything other than a physical machine. That when it's damaged/destroyed (when we die) it's simply over?

Sorry if this is done a lot, I don't frequent this section much.

If a loving all powerful god exists, surely he must wish to abolish evil and also be capable. So why does he not?

Don't claim free will, because free will had nothing to do with hurricane katrina, haiti, japan, etc.

He's lesser known... I saw him on youtube a while ago.

He has this routine about finding a cockroach missing a leg in his bathtub and trying to figure out how it got there. Also worrying about ghosts attacking him in the shower and how it would suck bc fighting a ghost naked would look ridiculous.

The whole thing was hilarious but I can't find him at all now.

I'm currently an engineering major but I really like the pure physics of it more than anything.

I hate courses like drafting and courses where I have to build things, I just wanna solve science problems, which I'm pretty good at.

I'm just worried that engineering is such a practical degree to have, and finding a job with a physics degree may be harder/less pay.

Manhattan College or Polytechnic Institute of NYU?

Best answer goes to the most reasoned out /detailed answer.

Thanks guys.

(major will be either electrical or mechanical engineering with a possible double major of physics if it matters)

My grade consists entirely of two things. Tests and lab reports.

My test average is in the high 90's but my prof is ridiculous in the way he grades lab reports. Factoring in my lab average my final grade should only be somewhere in the 80's.

However, even with lab's weighing me down to somewhere in the 80's I'm top of my class. There's only one other guy with test scores near mine and he hasn't even handed in the majority of the labs.

So he has to give at least one person in the class an A, right? Even if I'm technically in the B range.

Reason I ask is this professor is very strict with his grading, and I'm nervous over it.

Sorry if I rambled on....

I have 1000^logx

I need to rewrite it in terms of x without log.

I'm completely stuck...
