    The Derivative of a log of a trig function

    Yeah, you're right, forgot to square it in my post. I'll edit it.

    Double slit experiment with electrons

    I find this video to, if not explain, then at least illustrate the double slit experiment in a way that should be easy to understand.

    The Derivative of a log of a trig function

    z \in ℝ , didn't want it to get mixed up with x What does it simplify to using the half-angle formulae? Using the previously stated identities it should be possible to simplify the expression inside the logarithm to tan(x/2) EDIT: That's tan^2(x), not tan(x)!

    The Derivative of a log of a trig function

    Well, given that tan^2(u)=sin^2(u)/cos^2(u) , shouldn't it be possible to rewrite the equation into tan^2(z) , seeing as we have: sin^2(u) = 1/2 - 1/2 cos(2u) cos^2(u) = 1/2 + 1/2 cos(2u)

    The Derivative of a log of a trig function

    Wouldn't it be easier to use the trigonometric identities for cos^2(x) and sin^2(x)?

    Limit n approaches infinity of (1 + n)^(1/n)

    I would start approaching this by considering that: lim_(x→∞) for (1/x) = 0
