- Higher Math - Calculating the Minimum Perimeter of a Triangle
No triangle exists that minimizes that condition However, the infinum of the perimeters of all such triangles = twice the distance from (a,b) to the line y = x That's just an application of the triangle inequality after picking the first two points (one is on the line, the other is (a,b)) of any triangle
- Perimeter of a circle as a limit of inscribed regular sided polygon
Show that the perimeter Pn of an n-sided regular polygon inscribed in a circle of radius r is P n = 2 n r sin (π n) Find the limit of Pn as n approaches ∞ My attempt: The sum of the interior angles is π (n 2) If we apply the cosine law to find the length of each side of the n-sided regular polygon we find c 2 = 2 r 2 2 r 2 cos (4 π n π)
