  1. I'm wondering if "CuriouOne"s difficulty is with the English language. For example, in another thread (which was closed or I would responded there) "CuriosOne" repeatedly referred to "smaller pennies" where the correct phrase would be "fewer pennies". It is very strange that he posts questions about Calculus but makes0 basic algebra or even arithmetic mistakes.

    What help do you need or want? In order to help you we need to know what you already understand about this problem, what you are able to do, and what you are not able to do. In order to know that, we need to see what you have tried yourself. Surely you did not just post this without trying at all yourself? Please show us what you have tried.
  3. The first one is pretty close to being trivial! H2O is the only "acid" in the equation!
  4. As t goes to infinity the exponential goes to 0. Because the exponential is always positive and is subtracted, the "limiting charge" is when that exponential goes to 0 so is EC. You want to find t such that Q= -exp{-t/RC+ ln(EC)+ EC= -ECexp{-t/RC}+ EC= 0.99EC that is the same as -ECexp{-t/RC}= -0.01EC or exp{-t/RC}= 0.01.
  5. Now I'm hoping that all of your posts are silly jokes. Otherwise, you not only do not know but are refusing to learn from those that do know. And you have asserted repeatedly that "no one knows"! I think I am through responding to any of your posts. It does no good,
  6. So you posted this whole thread as a joke? I suspected that from the start. I didn't think a person would use so many words without having any idea what they mean! (And the word is "cease", not "seize"!)
  7. It looks to me like you don't know what "base" means here.
  8. To block radiation, use a lead plate. To measure radiation, use a geiger counter.
  9. No, I am not. But I think the term you want is "branching" rather than "non-linear".
  10. The "Multiverse" and "proto-universe" are hypotheses with very little experimental verification. Do you have more to say about them?
  11. Velocity and acceleration are "difference quotients"!
  12. That's obviously Wile E. Coyote who ran into the "monolith" while chasing the road runner. It even has "ACME" at the bottom!
  13. If we allow 1 as a prime number, we would no longer have "unique prime factorization". Now, 12= (2^2)(3). If we allow 1 as a prime number, 12= (1)(2^2)(3)= (1^2)(2^2)(3)= (1^3)(2^2)(3)= (1^4)(2^2)(3)= ....
  14. I believe that " this sentence is about itself being informative" WAS an example. Unfortunately, I have no idea what the sentence means! I suppose you could write "p-> (p-> i)" where "p" is "this sentence" and "i" is "is informative".
  15. Frankly it appears that you do not know what "limits" are! If you did, you would know that "24.999....." IS exactly 25. Taking a limit does NOT "involve two points", it involves infinitely many points. Taking "the limit as x goes to a" involves all the points between [tex]a- \delta[/tex] and [tex]a+ \delta[/tex] and, no matter how small [tex]\delta[/tex] is, there are infinitely many points between those points.
