What is the limit of the length of a side of a regular polygon that is inscribed in a circle?? HW help
are the sides of the regular polygon allowed to increase
yeah.. it can go up to infinity but the accordance should depend on the radius of the circle somehow
sorry, what do you mean by 'accordance'
|dw:1422521557949:dw| The side of a polygon inscribed in a circle is a chord (two points tangent to a circle connected by a line). A chord's length, c, is determined by its central angle, θ, and the radius of the circle, r. This relationship may be written as\[c=2r \sin \frac{ \theta }{ 2 }\]The central angle is determined by the number of sides, n, because each side (or chord) must be equal and must divide the circle into equal segments.\[\theta=\frac{ 360° }{ n }=\frac{ 2\pi }{ n }\]Plug that into the equation for chord length to find an equation representing the length, s, of a side of a regular polygon which has n sides.\[s=2r \sin \frac{ \pi }{ n }\]Then find the limit of the formula as number of sides, n, increases infinitely.\[\lim_{n \rightarrow \infty}2r \sin \frac{ \pi }{ n } = ?\]
