Find all real solutions of the equation \(\sin^2 x = -2 + 2\cos x\).
Math - Steve, Tuesday, December 4, 2012 at 6:50pm.
Since \(\sin^2 x = 1 - \cos^2 x\),
\[
1 - \cos^2 x = -2 + 2\cos x

# Topology
Topology is a branch of mathematics that studies the properties of figures in space under specific transformations. It is sometimes referred to as “rubber geometry” because it examines how geometrical figures placed on an imaginary “rubber” can be deformed when this rubber is stretched or bent.

Problem:
**Maximum Weight Sub‑set of Intervals with Capacity Constraint**
You are given `N` closed intervals on the integer line. The `i`‑th interval is described by three integers `L[i] , R[i] , W[i]` – its left end, right end (`L[i] ≤ R[i]`) and its weight.
You may choose any subset of the intervals. A chosen subse... | code_algo |
Problem
You are given an array `A` of `N` integers ( `1 ≤ N ≤ 2·10⁵` ).
You have to answer `Q` queries ( `1 ≤ Q ≤ 2·10⁵` ) of the following two types
* **Update** `1 L R X` – add `X` to every element `A[i]` with `L ≤ i ≤ R`.
(`|X| ≤ 10⁹`)

**Problem**
**K‑th Smallest Value in a Subtree**

Node `1` is the root.
Each node `i` has an integer value `a[i]`.
You have to answer `Q` queries of the following form:
```

For the subtree rooted at node `u` (including `u` itself) outp... | code_algo |
**Problem**
**K‑th Smallest Number on a Tree Path**
You are given a rooted tree with `N` vertices (the root is vertex 1).
Each vertex `i` has an integer value `val[i]`.
For each query `u v k` you have to output the `k`‑th smallest value among all vertices that lie on the **simple path** between `u` and `v` (bo... | code_algo |
**Problem**
You are given an array `A[1 … N]` of integers and an integer `K (2 ≤ K ≤ 100)`.
You have to process `Q` operations of two types:
* **Update** `1 i x` – set `A[i] = x`.
* **Query** `2 L R` – for the sub‑array `A[L … R]` output the number of **contiguous sub‑arrays** whose sum is divisible by `K`.
