Let \binomnr-1=28, \binomnr=56 and \binomnr+1=70. Let A(4\cos t,,4\sin t), B(2\sin t,,-2\cos t) and C(3r-n,,r^2-n-1) be the vertices of a triangle ABC, where t is a parameter. If (3x-1)^2+(3y)^2=α is the locus of the centroid of triangle ABC, then α equals | Watch the step-by-step video solution for this NIMCET PYQ.
