So....here goes some of the SHORTCUTS in complex number |z - z1| + |z - z2| = K---------(K = const).... (condition....co eff of z mst be same , z1 & z2 can be real ) then this is the e=n of an ELLIPSE IF coeff of z are diff....then it will be a PARABOLA 2) wen given..... coeff of x2 & y2 be same , the e=n will be of a circle if co eff of x2 & y2 both + ive then ELLIPSE AND if coeff of 1 is -ve then HYPERBOLA 3) In AP etc.... we all knw about arthmetic mean , GM and HM d in case of AM = (b-a)/(n+1) GM = (b/a)1/(n+1) BUT...wats n--? n is not the no. of total terms n is the number of INSERTED TERMS 4) in an AGP , 1st term will alwa
