1. Very easy question

simple question, if the derivative of cos(x) as x->0 is 1, the is the derivative of cos(3x) as x->0 = 1 aswell?
2. Having a little trouble, very typical question

thanks everyone, btw hallsofivy displacement is a vector, distance is not. just to cleat that up :) thanks again i understand the problem now
3. Having a little trouble, very typical question

oh I am sorry, it is suposed to say 100m North
4. Having a little trouble, very typical question

sry, i can't find the mistake your talking about, would that 85 be -115?
5. Having a little trouble, very typical question

im not use to working is 3D so i need some help you are going to a restaurant. you leave your apartement and take the elevator 30 m down, then 15 m south to the exit. then u travel 200 m east and then 100 m to the restaurant. what is your displacement. so what i did is: -30k -15j...
6. Simple question, tangent line

finally, got it
7. Simple question, tangent line

thanks for the replies, but i don't understand how the c.d is 2h(2+h)
8. Simple question, tangent line

but those are different terms, arent i looking for a common denominator?
9. Simple question, tangent line

i don't understand
10. Simple question, tangent line

thanks okay stupid mistake, now I am stuck again tho \frac{2}{2(2+h)}-\frac{(2+h)}{2(2+h)}*\frac{1}{h} comes out to \frac{-1}{h}}*\frac{1}{h} gives me -1/h which doesn't work, darn
11. Simple question, tangent line

really isn't calculus but that's the name of my class so, anyway I am having a problem here. i think its pretty simple I am just missing something. I am supposed to find the slope of the tangent line using one point and: slope of tangent line = \frac{f(a+h)-f(a)}{h} h\rightarrow0...
12. Circular motion question

nvrm, the it is F \propto f^2mr thanks tho
13. Circular motion question

doing a lab report on circular motion and was asked to make a combined proportionality statement, just asking yes or no, is this right? F_c \propto f^{2} \propto a_c \propto \frac{1}{m} \propto r where "F_c" is the centripetal force, "f" is frequency in Hz, "a_c" is the centripetal...
14. How do they know the universe is expanding

are you saying that space is infinite?
15. How do they know the universe is expanding

I see, so really the notion that the universe is still expanding today is an assumtion?
16. How do they know the universe is expanding

This stuff isn't fresh on my mind, but wouldn't the fact that we see continuous redshifting in galaxies billions of light years away relative to galaxies millions of light years away from us imply that the universe is still expanding in our present time? Sure the redshift we read on galaxie...
17. Hume's fork

Hume's fork: "Either our actions our determined, in which case we are not responsible for them, or the result of random events, in which case we are not responsible for them." Is there any philosophy that suggests we are in control of our own actions?
18. The golden rule a relative law?

sameandnot, the story of Daniel was just an example to prove that the Golden Rule was based on opinon and perspective. I didn't mean to imply that it was given to us to rule our societies and prove that it's flawed. Basically, the way I see, is that the Golden Rule is relative to any person's...
19. The golden rule a relative law?

In what way has he violated it? Most, probably the criminal would like to be treated with respect, goodness and justice. But what does he know about respect, goodness and justice? Does he know exactly as much as the judge? The jury? Anyone? How can the way you want to be treated be universal...
20. The golden rule a relative law?

Here's the unfolding you mentioned: You ask what is the source of conflict, I say the lack of virtue and rationality. You then ask, what is the source of lack of virtue and irrational thought? I do believe that this is the only meaningfull way to answer the tough questions in life, at...
21. The golden rule a relative law?

I do, BUT, the way you wish to be treated is your wish, and your wish alone. Ill agree that most people would like to be treated in a good and just manner, but, what is "good" and what is "just" is no longer absolute if you use one single person's opinion of the two. Do you see what I'm saying...
22. The golden rule a relative law?

The source of conflict, war and hate? First, I don't think war can be so easily associated with hate, because wars are caused mostly by conflict and selfishness. Either way, would you agree that conflict leads to war, as well conflict may lead to hate? If so, the we are looking for the source...
23. Hess' Law, checking my answer

thanks for all the help andrew
24. Hess' Law, checking my answer

I don't have the answer to this, and it's a big question so I'd like to know if I got it right. Thanks Determine the \Delta H value for reaction A: A)3CH_4 \rightarrow C_3H_8 + 2H_2 \Delta H=? Okay so I was given a reference table and used these two equations for Hess' Law...
25. Simple enthelpy question

sry my latex is messed up, the h should be capitalized and there should be a space in between the equation and the delta H o so it would? how come? because I understand it as yes, when you double the amount of reactants and products you need double the energy, but even so, the enthalpy change...
26. Simple enthelpy question

lets say u have: Ch_4 \rightarrow C + 2H_2 \Delta H + 74.9 kJ When you multply the whole equation by 2, does the change in enthalpy double? or does it stay the same? keeping in mind that it's reduced to kJ/mol... thanks 2Ch_4 \rightarrow 2C + 4H_2 \Delta H + 149.8 kJ ??
27. Quoting Plato

no it helped sameandnot, thanks, apreciate it

sorry that's not what i really meant, i meant did i missinterpret any of plato or aquina's philosophies
31. Proving absolute morals exist

I'd like to ask a question: Would you guys agree that IF we could understand our Purpose, then morality would be absolute?
32. Proving absolute morals exist

Besides for going in circles, is any of my reasoning false or illogical? just wondering...
33. Proving absolute morals exist

AKG, you are right and I agree with your critism, the only thing I would say in defence is that The Morals are given to us by god, but we can only find them in our conscience, which is innate. God has given us a purpose, I tried to prove that if morality where to exist then a purpose would...
34. Proving absolute morals exist

Hi, I've been reading a lot about philosophy to write an argumentative essay on Absolutism vs. Relativism in favor or moral absolutism. Unfortunatly I have come to the point where I'm thinking too hard. I am not good enough in philosophy (very new to it!) to prove that absolute morals exist, I'm...

cesium can u give me some me keywords about these compounds so that i can look them up and read about them? thanks
36. Objectivism and relativism

here's the quote i read "My philosophy, in essence, is the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute. [1]"

anyone?...
38. The golden rule a relative law?

I apreciated your replies. I think because of Livingod's statement, this discussion could take a turn to meta-ethics: What is "good" treatement? Can we simplify the rule to "treat people good"? The Golden (not silver) rule is "treat others as you want to be treated." My question is, isn't...
39. The golden rule a relative law?

maybe i should say that the golden rule is not a law, just a rule, forgive me.
40. The golden rule a relative law?

as stated in the Bible, "Do unto others as you would have others do unto you" or simply "Treat others as you want to be treated." is the golden rule. But since the way you wish to be treated is you're choice, would that make "Treat others as you want to be treated." a relative law? Can't...
41. Objectivism and relativism

in ayn rand's philosophy of objectivism she says that a man's only absolute is his reason. Since no man has the exact same reasoning (or intuition) would this imply that mankind's reason is relative? and if you were an objectivist, would that mean you would also be a relativist? thnx
42. Free body force question

thanks for the diagram i really apreciate it, i got the right answer now, but not exactly in your way. once i saw how u resolved the tensile force, i just did Tsin(35)=4.2e-3, and Tcos(35)=6.0e-3, solving those gave me the x and y components to the tensile force (they were both equal so i didnt...
43. Free body force question

thanks fermat, but i don't understand wat u did...
44. Free body force question

okay, but wat about finding the tension, how do i do that?
45. Free body force question

a small spider weighing about 6.0e-3 N, hangs on its thread from the branch of a tree. A horizontal wind blows the spider and the thread to and angle of 35 degrees from the vertical. a)find the horizontal force of the wind on the spider b)find the tension in the thread i got a, here's wat...
