अवधारणा:

वक्र का वरसाइन

वरसाइन एक वृत्त के आर्क से एक जीवा के मध्य बिंदु की लंबवत दूरी है

विभिन्न इकाइयों में एक वक्र की त्रिज्या और वरसाइन के बीच का संबंध नीचे दिखाया गया है:

\(V = \frac{{{C^2}}}{{8R}}\) ............. (V, C, R समान इकाइयों में हैं, कहते हैं, m या cm)

\(V = \frac{{125{C^2}}}{R}\) ......... (mm में V, m में C, और m में R)

\(V = \frac{{1.5{C^2}}}{R}\) ........... (फीट में C और R  और V इंच में)

जहाँ,

V  = वक्र का वरसाइन

C = जीवा की लंबाई

R = वक्र का त्रिज्या
