Отношение длин касательных к эллипсу равно отношению радиусов вписанных окружностей (синих) и корню кубическому из отношения радиусов соприкасающихся окружностей (красных), касающихся эллипса в тех же точках. Второе утверждение - теорема Лиувилля.

So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. Oh no. There’s a certain degree of myth-making around what exactly went on, so take everything that follows lightly. Telegram was originally launched as a side project by the Durov brothers, with Nikolai handling the coding and Pavel as CEO, while both were at VK. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website.
