Each of the 4 sectors is 45 degree, with radius of 1/sqrt(2), so sum of their areas is equal to a semi-circle with radius of 1/sqrt(2), which is 1/2 * pi * 1/2 Each of the dart-shape can be converted into a parallelogram as shown in yellow color.
Solution 3 (Partial Proof) First, we can assume that the problem will have a consistent answer for all possible values of . For the purpose of this solution, we will assume that . We first note that . So what we are trying to find is what mod . We start by noting that is congruent to .

We know that there are ways to select two segments. The ways in which you get 2 segments of the same length are if you choose two sides, or two diagonals. Thus, there are = 20 ways in which you end up with two segments of the same length. is equivalent to .
Solution 1. and . Therefore, we have the equation Factoring out a gives Factoring both sides further, . It follows that if , , or , both sides of the equation equal 0.

Problem 3 On a particular January day, the high temperature ...What is the 2008th term of the sequence? Solution. Since the mean of the first n terms is n, the sum of the first n terms is n^2. Thus, the sum of the first 2007 terms is 2007^2 and the sum of the first 2008 terms is 2008^2. Hence, the 2008th term is 2008^2-2007^2. 2017-01-05 21:20:00. ….
