If α is the angle between the polar ray and the tangent at the point of commencement of a lemniscate curve, the equation of the curve, is-A-l = ksin αB-l = ksin 2α C-l = ksin 3αD-l = ktan 2α E-l = kcos 2α-B-l = ksin 2α

Question

APTITUDE CRACK · Accepted Answer

B l = ksin 2α  The shortest distance between the point of commencement and point of a tangent I&#39;m circular curve is? At the point of commencement. The curve takes only &amp;alpha angle. not 2* &alpha;. So, option A is the right one. Option (b) will be correct, as the length of lemniscate curve is: L=3.934r&radic;(sin2a).
