    Jose Z posted the thread Mathematical thinking or gene? in Math Odds & Ends.
    What's the best math literature to read, whether fiction or non-fiction, for cultivating mathematical thinking? I have reserved "The...

    Jose Z posted the thread learning sequence to follow in Intermediate/Advanced Algebra.
    Currently, I am reviewing algebra. I have forgotten what sine and cosine are, even though I took a few math courses in school. I wonder...

    Dr.Peterson replied to the thread Checking for radical equation.
    Yes, that is a big part of what was wrong with that. But you didn't just say that the equation is a function, but that something is a...

    mrtwhs replied to the thread Checking for radical equation.
    It does not. Do you mean the function f(x)=\sqrt{x^2-2x+4} or the function f(x)=x ? These are two totally different functions. I...

    askan replied to the thread Checking for radical equation.
    If I am understanding you correctly, functions are only equal to mathematical expressions e.g. 4x, 2(x-1), not equations. So function of...

    Part of the trouble here is that you are using words incorrectly. I don't know what the bold phrase is intended to mean, but it is not...

    The funniest equation I ever saw was 2^n+7^n+8^n+18^n+19^n+24^n=3^n+4^n+12^n+14^n+22^n+23^n \text{ for } n =0,1,...,5 But back to...

    askan replied to the thread Rational exponent.
    I wasn't doing my work here under the assumption that we could only take the positive or negative root, but I understand your point now.

    I wasn't sure which side of the equation (the one in the ss that I posted) to render equal to f(x), to represent a function of the...

    just realized that this one is trivial: (n+2)^2 = n^2 + 4(n+1) :confused:
