**This image shows 1,000 line segments. For each \(i=1,2,3,\cdots,1000\) the endpoints of the \(i\)-th line segment are:**

**\[\left(\cos\left(\frac{2\pi i}{1000}\right), \sin\left(\frac{2\pi i}{1000}\right)\right)\]**

**and**

**\[\left(\cos\left(\frac{4\pi i}{1000}\right), \sin\left(\frac{4\pi i}{1000}\right)\right).\]**
