    "The Chase" Quiz Show -- probability of being caught by the Chaser

    Hello everybody. :) If any of you have seen the quiz show "The Chase", then you will understand the background to what I am about to describe. If not, here are wiki links for the original UK version and the similar US version. My question is inspired by the "head-to-head" or "individual chase"...

    Finding the value of each color?

    Some of those equations look inconsistent to me.

    Pre calc review - interval notation

    I'm surprised no one's mentioned the incorrect use of the square bracket to end the set.

    Finding the co-ordinates of the 3rd point of a triangle given this?

    For any triangle, there are 3 side-lengths and 3 internal angles and 3 (potential) coordinates. From your diagram, you may be expecting the one and only answer, or you may be tempted to think that there are 2 answers if you consider the order of ABC as being unimportant - but from the...

    Showing a sequence converges to 0

    Thanks. Good to know. This is exactly what I was trying to hint at in post #8. Still not fully understanding your post #7 though! No, not getting this at all. Why must n=2 be part of the base assumption? The statement is true when n=1 (true for n=0, in fact - not sure I would reach out for...

    Showing a sequence converges to 0

    I think I may be showing my inexperience here, but I'm struggling to see how the other posts are helping (although I'm sure they will be doing just that!). But personally, my thoughts on it are: ...you have started by stating what you need to prove. Surely you should be stating what you...

    Does this function have a name?

    Why is that? That surely just gives the length of the straight line from (0, 0) to (1, y). The curve you are looking for is not going to be of that form.

    How can a transcendental number be a base?

    Well, that's the first time I've seen a 2 and a 3 in binary! In any case, your arithmetic is wrong. Please read your posts before posting! :-p

    Trying to differentiate using function of a function/Chain rule

    should read as: \frac{dy}{du} = 3u^2 and \frac{du}{dx} = -2\sin 2x but other than that, it looks fine.

    What proof technique can be used to solve this problem involving odd numbers?

    Actually, yet again, I'm an idiot! "For all x in Z, prove that if..." is equally as valid as "Let x be in Z. If..."

    Simple geometric series question

    I'm still eagerly awaiting the question about a geometric series! :-p

    What proof technique can be used to solve this problem involving odd numbers?

    "For all x in Z..." is NOT what is in the question according to your picture of it. This means something entirely different.

    Calculating the Area Under an Inexisting Curve?

    No, I didn't think it was a particularly great catch. As I'm sure you know, there are extremely simple functions that have discontinuities and yet are integrable. A simple step function, for one.

    Calculating the Area Under an Inexisting Curve?

    Hmmm... you sure about that?

    Understanding the Absolute Value Formula: Is it a Rule or a Myth?

    I think you have your x and y the wrong way round there.
