I didn't see these questions. Is the GRE supposedly the same everywhere?

I think you forgot +C. I think pi/4.

PS I didn't see that question on my GRE

Sorry I haven't heard of this. This is taken from the test in U.S. The second problem is among the last few questions, it seems.

Also, I think that's a little unfair that they would test different questions for the same test, especially since I thought the second problem was one of the hardest on the test. But I suppose they figure out the distribution by seeing how everyone performs on each version.

Problem 2 I remember it saying that [deleted]? But i didn't really attempt this problem during the test because I was running out of time.
I got the same answer as you did for the first question. For the 2nd one, I think we would need [deleted].

Anyone remembers the given answer choices of a question involving the [deleted]?

pi/4, it's a [deleted]

When you took the test, you all had to sign an agreement stating that you would not discuss the exam problems.

Do you mean [deleted], that would be pi/4.

Not sure whether it's [deleted]. Somehow I don't remember seeing [deleted] as one of the answer choices. Either case, I think I got this one wrong ([deleted], but could not figure out the [deleted] man. How ridiculous that is:D)

If I'm thinking of the same problem, it was an [deleted], not a [deleted], with all [deleted]. The [deleted] was smaller than all but one of the answers, so it was that one :D

That one is different though...And it's all telescoping in that one...But I think we should stop discussing in public here:D
