Question

find the limit as x approaches 0 for cos(2x)/x

Answer 1

Use L'hopital's rule

Answer 2

hmmm actually

Answer 3

You just need to do L'hopital's rule twice and you get the answer.

Answer 4

cos(2x)/x => -2sin(2x)/1 => -4cos(2x) = -4 therefore as x approaches 0 of cos(2x)/x is equals to -4

Answer 5

hmmm lemme remove those.... since... that's off
