My first quiz, let me know what you think!

good one....... accept Liebnitz too!!!
Apr 19th, 2010 at 12:34 GMT
good job... i can have no complaints.
Apr 19th, 2010 at 17:19 GMT
Thanks manutd, i just put in a bunch of potential misspellings and accepted them.
Apr 19th, 2010 at 22:00 GMT
Very nice variety! $500 accepts 13, and -13, but doesn't accept +-13. I thought $100,000 was quite hard and I'd have to try to solve it, until I realised you hadn't specified real roots only. So it was very easy! I'll take cash, btw. $1,000,000.
Apr 19th, 2010 at 23:26 GMT
Good quiz; only issue - you don't need to have "go" at the beginning :) Got stuck at Leibniz so can't comment on the questions after that - would have put 2k and 4k other way around but otherwise questions seem in the right order etc. too! :)
Apr 20th, 2010 at 00:16 GMT
Good call on the plus/minus 13...and I wasn't sure about the GO, I've seen quizzes where that is a requirement so I put it in there just in case. Thanks.
Apr 20th, 2010 at 03:11 GMT
I think "What type of differential equation" is way too vague. At first, I typed in ordinary, which is definitely correct, but it wasn't accepted because it's not what you were looking for. Maybe "Classify the order and linearity of" would be better. DEs have more classifications than just order and linearity. There's dimension, degree, partial vs ordinary, etc.
Apr 20th, 2010 at 21:02 GMT
About the "GO" thing: that's needed on fancy quizzes that use the bonus answer system to make different questions appear depending on what answers you give. A quiz like this, just using one of the predefined setups the way it was made to be used, shouldn't need it. Nice quiz, though! (coming from a math grad student :-) )
Apr 20th, 2010 at 21:03 GMT
Great quiz! I'd love to see more quizzes like this. However, I have to agree about the ODE one. There are a dozen or so terms that could classify the DE and linear was definitely not the first that came to mind.
Apr 21st, 2010 at 01:07 GMT
Thanks for the help- I got rid of GO, and ended up changing the DE question; asking it as "What order is this DE" seemed too similar to the last one, so I changed it to "What is the derivative of cosh(x)", but that may be too easy, we'll see.
Apr 21st, 2010 at 20:38 GMT
i couldnt remember opposite of cosine
Apr 22nd, 2010 at 01:19 GMT
Not bad for a first quiz. I had to look up the $8000 answer (sorry but after Cartesian and polar, I'm out of bullets), and I think the $100K and $500K might be a bit overpriced. A couple suggestions: (1) for the $25K question, accept the function equation itself rather than the name. I spent two minutes typing in stuff like "f(x) = e^x" and "power(e,x)" before accidentally typing the right answer. (2) The $1M question probably ought to be changed. No way would I remember what the lower bound was, but the right answer is also the most obvious guess. That's the problem with Sporcle quizzes: if a difficult answer is also a prefix-stem to another, easy answer, the player gets credit for both (which is why nobody ever misses "Dominica" when a Caribbean nation is called for.)

I like this quiz - it's nice to see a math quiz which isn't just a bunch of nasty arithmetic! I'd order the questions a bit differently for difficulty, and I agree with strags11's points, but overall very nice.
Apr 27th, 2010 at 15:22 GMT
Though I knew what you were going for, I would argue that "arithmetic" is the right answer to the $1000 question. Normally I wouldn't complain about this, but your later questions suggest that you're sophisticated enough to know what algebra *really* is.

For independent you should also accept Disjoint or Mutually Exclusive.
Apr 28th, 2010 at 03:41 GMT
I really love the quiz! I got so sick of the 1 minute arithmetic ones. Speaking of which, I agree with ostroffj, the answer for $1000 is definitely arithmetic. after I typed it and it didn't pop up I was super confused, especially considering the mathematical know how displayed later on. I also don't particularly like the $8000 question. It's just something that (as I am sure you know) is referred to without its technical name so much that even as a math major it slipped my mind completely.
May 2nd, 2010 at 00:22 GMT
No coordinate system I can think of uses r, theta, phi. r is the planar/cylindrical radius, and rho is more commonly used for the spherical one. Also, "exponential" is too general an answer for the $25,000 question, as there are many many kinds of exponential functions who are not their own derivative (e^2x for example). The correct answer there is just e^x (or, if you want to get technical, Ce^x). Other than these issues, nice quiz!
May 7th, 2010 at 17:06 GMT
Alright- thanks for the comments- the major issues seem to be with the 1k (adding arithmetic, done), 8k, moving the 100k and 500k down, and finding a new million-dollar question. I wanted something for the million dollars that is fairly significant mathematically, so I'll get to that. About the 25,000 dollar question, the answers that I have it accepting are Exponential/e^x/the exponential/e^t/exp(x)/exp(t), I did not think to put f(x)=e^x and all of those variants as well, I will do that. I will keep exponential as an accepted answer however, even though it is a bit too general, it seems unfair for a quiz-taker to have to type the actual equation when there's so many ways to do so. Thanks for the feedback, I'll get an updated version up later today.

accept polar graphing for spherical
Jun 9th, 2010 at 09:25 GMT
@Hooby. Polar is 2D
Jun 10th, 2010 at 19:32 GMT
@SuperPokenerd- Disjoint/Mutually Exclusive is incorrect. If events A and B are disjoint/ME, then P(A and B)=0, not P(A)*P(B). In fact, disjoint/ME events are essentially the exact opposite of independent events since one event can be completely determined by another event.
Jul 14th, 2010 at 08:40 GMT
Accept ce^x for that one question. @WyvernSabres - The polynomial either has four, two, or zero real roots, so it wouldn't be hard to guess if that were the case.
Aug 6th, 2010 at 16:25 GMT
in addition to exponential, you shoudl also except either just e or at least ex (i.e. e^x)
Aug 25th, 2010 at 00:19 GMT
got through 15k off of what i know (i'm in 10th grade, pretty good right?), then i used wikipedia to find the rest (is that cheating?), anyways, my point is you should reduce the time, so people (like me) dont have time to do that, and people actually get to where they know
Nov 16th, 2010 at 09:32 GMT
I like this quiz in that it takes you from preschool/kindergarten calculations to undergraduate studies, which is where I am now. I just took ODEs and learned what the Laplace Transform was very recently, although I would have probably guessed 0 at some point anyway.
Nov 19th, 2010 at 01:14 GMT
@humdawgger: maybe accept "Gottfried Leibniz" for "Leibniz"? (especially since you gave Isaac Newton's name in full in the clue, my reaction was automatically to reply in the same style)
Feb 19th, 2011 at 13:22 GMT
When you take the square root of 169, because it's a mathematical operation, there's only one answer (i.e. 13) so -13 and +- 13 are incorrect (the only time it would be +- 13 is if you had x^2 = 169, because there are two possible values for x).
Jun 13th, 2011 at 18:36 GMT
Love the quiz. A minor nitpick: for the $100,000 question, functions do not have 'roots' - you should ask about the zeros of the function f(x), or the roots of the equation f(x)=0.
Jul 30th, 2011 at 17:36 GMT
I spent almost all of the quiz typing different ways of saying polar coordinates - 3d polar; three dimensional polar etc... at no point did I remember "spherical polar" :P
Oct 20th, 2011 at 18:55 GMT
would be better if it was a wrong answer quiz, but well done!
Apr 10th, 2012 at 19:33 GMT
Million dollars off a guess on the last question... lol.
