    Undergrad Euclid Proof of Infinite Primes

    \frac{kn+1}{k}=n+\frac{1}{k}, where n is an integer. If p is a factor of k, then \frac{kn+1}{p}=n'+\frac{1}{k}, where n' is an integer.

    How Do You Solve for x in a Midpoint Geometry Problem?

    You know that RT= 4x-6. You should be able to get an equation with one variable.

    Discovering Valid Solutions for Max/Min Values of a Trigonometric Function

    You want to divide both sides of the equation by some C such that \sin(\alpha)=\sqrt{3}/C and \cos(\alpha)=1/C. (So that we can use the trig summation identity) Then it must be true that (\sqrt{3}/C)^2+(1/C)^2=1. It follows that C^2=3+1. So in general, for y=A\cos(x)+B\sin(y), you want to...

    Discovering Valid Solutions for Max/Min Values of a Trigonometric Function

    This doesn't answer your question, but I find it to be another nice way of solving the problem. Notice that \sqrt{3}^2+1^2=2^2. So If you divide both sides of the equation by 2, you get...

    Show that 2^(1/3) + 3^(1/3) is irrational.

    The hint suggests to find a polynomial with integer coefficients. You have the right idea cubing, but there's a little more. You found x_0^3=5+\sqrt[3]{6}(\sqrt[3]{2}+\sqrt[3]{3}). But you can simplify that even more, by substituting x_0 in for \sqrt[3]{2}+\sqrt[3]{3}, to get...

    Job Interview Dilemma: Choose Physics Modeling or Defense Contractor?

    This question amazes me. If we had said, 'no, it is unlikely that you will get the position,' would you not go? Bombed the interview on purpose? Cried?
