Best ResponseYou've already chosen the best response.0Use the squeeze theorem \[\lim_{x\to\infty}\cos((\pi/x)x)/x = \lim_{x\to\infty}sin(x)/x = 0 \] It follows that; \[\lim_{x\to\infty}\cos(x)/x = 0 \]

Best ResponseYou've already chosen the best response.0Be careful. As x approaches zero, (cos x)/x gets larger and larger. So limit is +infinity.
