Hey its quite easy but it is applicable only for indeterminate forms ie.0\0 and Infinity\infinity only in this rule u should diffrentiate each term till u remove the indeterminate form . for ex . lim x-e lnx-1\x-e. So solving this by l hopital rule bcoz this is 0\0 form we get ...... Diff lnx =1\x and all 1 and e are const so 0,then diff x =1 so the ans is 1\e.....
