lim       sin(π+h)- sinπ                                      h→0     —------------                                                          h

1:Please evaluate the following (the long straight line represents division sign):

  A:                                lim       ln(?+h)- ln?

                                     h→0     —------------

                                                         h

   B:                               lim       sin(π+h)- sinπ

                                     h→0     —------------

                                                         h
