Hey guys my friend hypothetically was interested in how one would go about rendering the water supply to a major city unusable.

It's for a hypothetical school science experiment.

Sad!

Fucking code monkey get the fuck out of my field.

Can someone PLEASE explain convergence and divergence to me? I'm not fucking understanding it.

I just want to die.I cant bear this torment anymore.Why all of the things that provides peaceful,fast and certain death like guns,pentobarbital,seconal are illegal man i dont understand.Those satanic countries torturing me by forcing me to keeping alive.Yhis cleaning Ocd takes 12-18 hours of my a day,i cant sleep well because of anxiety,i can only piss and eat once a day,i can only poop once a 1,5 or 2 week.I cant do any work because there is no time to do some work,ı am living like a parasite and no one havenot enough tolerance for me anymore.I am tired.I am a slave to my mind.I dont want to be slave to my small brain anymore.I also dont want to commit suicide.I just want to use that idea as a relaxing thing.If ı would have pentobarbital,ı would gain enough braveness for not doing any compulsion anymore.I would think like If things gets worser than before,ı have an exit way and nothing can force me to stay alive and suffer.I dont want to spend my time to cleaning anymore.I want to east piss and shit like a normal person.I dont want to keep all of those shits in my guts with a intense stomach-ache anymore.I want to live work shit and eat like a normal healthly person.And this the only way.Please guys help me,i am misarable.I am considering dehydration as a suicide method.Anyone in here tried it before? And which accesible drugs can provie a peaceful and certain death to me.Dont say amitriptyline because it cannot provide a certain death and it may not be peaceful,i dont want to wake up in a hospital bed after committing suicide.

the derivative of a quotient is always given by the quotient rule.

L'hopitals rule is the following:

If I want to find the LIMIT [math] \lim_{x \rightarrow c} \frac{f(x)}{g(x)} [/math] but the limit is indeterminate, ie [math] \lim_{x \rightarrow c} f(x)=g(x)=0 [/math] or [math] \lim_{x \rightarrow c} f(x)=g(x)=\infty [/math] THEN [math] \lim_{x \rightarrow c} \frac{f(x)}{g(x)} = \lim_{x \rightarrow c} \frac{f^'(x)}{g^'(x)} [/math]

MFW people are crediting Hawking with the idea information is stored on black holes boundaries.

Did Hawking just fucking rip off Leonard Susskind/Gerard t'Hooft's holographic principle?

I'm back lads, I fucked up. This will be the first exam I have failed in my entire degree. Should I just commit sudoku?
