By definition, y0 is a limit off x-->x0 when for any xn-->x0 f(xn)-->y0. now we pick two sequences xn1=2pi*n1 xn1-->infinity cos(xn1)=1 for any n1. xn2=pi/2+2pi*n2, xn2-->infinity, but cos(xn2)=0. contradiction.
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
