Q. the value of lim x tends to k- x-[x] is A. lim h tends to 0 k-h-[k-h] = what to do next sir in book they are doing like this = lim htends to 0 k-h-(k-1) = 1 how are they puting 1 over ther ? plz explain. Share with your friends Share 0 Sanjay Kumar Manjhi answered this Dear Student,limx→k-x-[x]Here limit is k-, which is Left Hand Limit.Now,Let h→0⇒x→k-hNow,=limh→0-(k-h)-[k-h]As we mentioned earlier it is a Left Hand Limit. So even if k is a integer if we take left hand limit.Greater Integer Function will reduce it to -1.So,=limh→0-(k-h)-[k-h]=limh→0-(k-h)-(k-1)=k-(k-1)=1Regards. 1 View Full Answer
