Preparing for Higher AIME+

PhoenixMathClub 5

N an hour ago by Andyluo

Hello, I am going to be a 7th grader next year and I really want to qualify for USAJMO in 8th grade, so far I have these goals reached

1. AMC 10 Honor Roll A and B 2025
2. AMC 8 DHR and HR
3. AIME 3 :(

This year on AIME something happened and I got a 3 :( on the AMC's I got a 105 on AMC 10 A and I got a 114 on AMC 10 B. I want to improve mostly on AIME but since the AMC 10 is coming up quicker what would you guys recommend for getting 110+ on both of the AMC 10's and getting a 6+ on AIME? So far I am only doing Alcumus and have no books so far.... Checking the table of contents on the books Alcumus provides the same topics. I was thinking to take WOOT 1 and AMC 10 Problem Series.

Calculus BC help

5 hours ago

So basically, I have the AP Calculus BC exam in less than a month, and I have only covered until Unit 6 or 7 of the cirriculum. I am self studying this course (no teacher) and have not had much time to study bc of 6 other APs. I need to finish 8, 9, and 10 in less than 2 weeks. What can I do ? I would appreciate any help or resources anyone could provide. Could I just learn everything from barrons and princeton? Also, I have not taken AP Calculus AB before.

A semicircle k with radius r is constructed over the line segment ST. Let D be a point on the line segment ST that is different from S and T. The two squares ABCD and DEF G lie in the half-plane of the semicircle such that points B and F lie on the semicircle k and points S, C, D, E, and T lie on a straight line in that order. (Points A and/or G can also lie outside the semicircle if necessary.)
Investigate whether the sum of the areas of the squares ABCD and DEFG depends on the position of point D on the line segment ST.

Maximizing the Sum of Minimum Differences in Permutations

chinawgp 0

Today at 10:20 AM

Problem Statement

Given a positive integer n \geq 3 , consider a permutation \pi = (a_1, a_2, \dots, a_n) of \{1, 2, \dots, n\} . For each i ( 1 \leq i \leq n-1 ), define d_i as the minimum absolute difference between a_i and any subsequent element a_j ( j > i ), i.e.,
d_i = \min \{ |a_i - a_j| \mid j > i \}.

Let S_n denote the maximum possible sum of d_i over all permutations of \{1, \dots, n\} , i.e.,
S_n = \max_{\pi} \sum_{i=1}^{n-1} d_i.

Proposed Construction

I found a method to construct a permutation that seems to maximize \sum d_i :
1. Fix a_{n-1} = 1 and a_n = n .
2. For each i (from n-2 down to 1 ):
- Sort a_{i+1}, a_{i+2}, \dots, a_n in increasing order.
- Compute the gaps between consecutive elements.
- Place a_i in the middle of the largest gap (if the gap has even length, choose the smaller midpoint).

Partial Results

1. I can prove that 1 and n must occupy the last two positions. Otherwise, moving either 1 or n further right does not decrease \sum d_i .
2. The construction greedily maximizes each d_i locally, but I’m unsure if this ensures global optimality.

Request for Help

- Does this construction always yield the maximum S_n ?
- If yes, how can we rigorously prove it? (Induction? Exchange arguments?)
- If no, what is the correct approach?

Observations:
- The construction works for small n (e.g., n=3,4,5,...,12 ).
- The problem resembles optimizing "minimum gaps" in permutations.

Any insights or references would be greatly appreciated!

You're on the best website there is to learn math...Khan Academy is a distant 2nd and BA is good too but it only goes to 5th grade stuff

mathdash has harder problems than alcumus and you can find user-created contests and mocks on there, highly recommend it
