    Is Pre-Calculus Harder Than Calculus?

    This is what I have heard from everyone as well at my school (University of Florida). I don't really think I can venture an opinion because I found both to be easy. But if you understand how precalculus really well it makes calculus much easier.

    Reason why multiplication gives fraction of a number

    Division and multiplication and all things mathematical are created and defined by man. Trees are not concerned with 1/2 of their apples, trees in fact do not think. Cheetahs do not calculate a minimum velocity required to catch their prey. Rocks do not count. There is no other possible way...

    Numerically solving coupled DEs?

    Remove the dimensions and write a program to do RK4 unless this is just for a class in which case RK2 or Euler's with really small step is easier.

    Explanation of the Determinant

    You can find a general definition for a determinant http://en.wikipedia.org/wiki/Determinant#General_definition_and_computation". I didn't see someone else mention this way of looking at it but it seems pleasant to me since it is the definition.

    Calculus II is giving me a hard time

    Completely normal, the numerical evaluations should be trivial, the only help a calculator would be is if it could integrate symbolically but that would defeat the purpoes of going to calc 2, likewise as calc 2 is usually half methods of integration and half infinite series an integral table...

    I made a change regarding my career plans

    In America the situation for biomedical engineers is apparently not good. Schools are producing a lot of them and there are not a lot of positions in the biotech field that require a PhD most only require you to listen to the one PhD who works with you and be a chimpanzee. Good luck though.

    Does this Integral have an Elementary Solution

    I cannot seem to get anywhere with this integral I was wondering if anyone could provide insite into a special function or some technique I overlooked (only tried integration by parts and it got me nowhere). Also, forgive me for not knowing how to format it so that it appears pretty...

    Schools Remarks on AP courses in high school

    I go to UF both classes (calc 1 and 2) are a total waste of time if you know calculus. I retook the Honors version of the series after being in your position, just skip straight to calculus 3 and then start in on linear algebra. If you actually know calculus you will be fine.

    Solving Logarithms: Find Where You're Going Wrong

    Logarithms have the property that log(a)-log(b)=log(a/b) if they have the same base. So you do this to combine the logs, next you undo the logs by raising the base of the log to the power of both each side i.e. if log(a/b)=c where c is a constant then a/b=k^c where k is the base of the log...

    Thermodynamics: gas for stirling engine + liquid with high density

    Just make a very concentrated solution of NaCl will be very dense and has pretty much infinite solubility so you can make it as dense as you like. Don't really know anything about gases off hand though.

    Programs Unsure which second major is better complement.

    Chemical Engineering, my decision was initially based on a desire to be in the pharmaceutical industry it seemed most appropriate.

    Programs Unsure which second major is better complement.

    I am interested in biotech and nanotech and cellular engineering primarily. After graduation I am definitely going to grad school possibly for MD/PhD. My main career goal is to do research, but ideally I would be head of a start-up company. So my question is which is probably a better...

    Apparent impossibility of uniform magnetic field

    Did anyone ever read any of Feynmann's stories about when he went to Brazil? Just thought it was appropriate here.

    Are Philosophical Discussions on the Nature of Universe in Line with Physics?

    I read this thread and it looked like a bunch of people who are interested in philosophy just making stuff up about the nature of the universe. Are they just making assertions or does what they say agree with physics? https://www.physicsforums.com/showthread.php?t=103874" Thanks in advance
