Dr.Peterson replied to the thread Induction theorem.Presumably you mean, that you must prove both the base case and the inductive step, that if P(k), then P(k+1). If you proved the... -

Dr.Peterson replied to the thread Limit with Absolute.What you've done there is to assume x>0, so the limit you find is the limit from the right. Now assume instead that x<0, rewrite the...

MIs it mandatory to have P(1) to be proven true before we prove P(k+1) to be true? If P(1), P(2), P(3) are not proven but P(4) onwards...

KThe function f(x) = \frac{2x-|x|}{|3x|-2x} is not continuous at 0. As is often the case, its limits are different for x<0 and x>0. Have...

PThis post may also in time help others! Think of an "Intersection" and assume the traffic lights are malfunctioning. All traffic should...

NI have a problem understanding limits with absolute. \lim_{x\to 0}\frac{2x - |x|}{|3x| - 2x} If I compute the limit \lim_{x\to...

NDo you think it's easy? I think some of the others are a little more straightforward. Have you worked it out yet, either from the...

NI didn't know about "stars and bars" mentioned by @Dr.Peterson, but my approach seems equivalent: Given a subset S_1 of r numbers...

Mmrtwhs replied to the thread Permutation and combination when letters are repeated.You are correct. I've kept all four letters apart. However the OP's original wording seems to allow HH as well as RR. So my answer...

blamocur replied to the thread Permutation and combination when letters are repeated.I believe I've solved it, but I am not too proud of the solution: it considers 7 different cases for placing H's :confused:

blamocur replied to the thread Permutation and combination when letters are repeated.My brute force script confirms the 88200 answer under this assumption.

Dr.Peterson replied to the thread Permutation and combination when letters are repeated.It looks like you are using different methods for the two problems. It would be helpful to apply the same method to both, which could...
