    Is my Predicate Logic Solution Correct?

    I have the sentence: No American who hasn't met any Canadian's knows Canada. The teacher gave the correct answer as being: Vx-Ex((Ax ^ Cy ^ Mxy) -> -Kxc) Would this version also work?: -ExEy(Ax ^ Kxc ^ Cy ^ Mxy) or is it supposed to be: -ExEy(Ax ^ Kxc ^ Cy ^ -Mxy) After...

    Draw a complete truth-table for the following sentence

    Ya I wasn't sure what to do with if cases. I think I understand it now. Doesn't valid mean it is true under all interpretations?

    What is the Significance of Multiple Time Derivatives in Physics?

    If the derivative of displacement if velocity, and the derivative of displacement is acceleration, does the derivative of acceleration give you anything? We were trying to think of something in class today but couldnt.

    What Can We Truly Know About Our Existence?

    the reason i was arguing the existence of matter was to get ur13 to think differently about existence. I originally asked if you could prove you exist and then the whole issue of "i think therefore I am" came up, so I was arguing that maybe there is no thought and that its just the compilation...

    What Can We Truly Know About Our Existence?

You can't say that apple exists just because it exists because you can't justify a statement by saying "just because it does". That is the point I was trying to get...

    What Can We Truly Know About Our Existence?

    You can't prove that things have always excisted just because of carbon dating or texts. The texts and all the fossils with a certain carbon make up could have been created as soon as you were born to accommodate your entire life. Going along with what Marostos was saying, the reason we can't...
