        <p>Считаю небесполезным отметить одно свойство стереографической проекции, хотя и не открывающее новых путей для решения задач, но могущее способствовать большей точности решения некоторых из них.</p>

        <p>I consider it useful to note one property of stereographic projection, which it does not open up new ways for solving problems, still can contribute to greater accuracy in solving some of them.</p>
