1 14/10/25 2 ======== 3 4 Limits 5 ------ 6 7 - say that f(x) is defined when x is close to some value a, the limit of f at A is C if f(x) becomes very close to c. 8 - FIG1 shows this 9 - FIG2 shows the method 10 - note we choose values close to the limit, to sub into X 11 - FIG3 shows an example method 12 - note because the function was defined at 3 it could be solved 13 - FIG4 shows a right oriented limit, noted by the plus, this means only view values come from the right hand side 14 - same thing works for a left sided limit 15 - FIG5 shows an examples of the sign functions 16 - FIG6 shows an example of solving inf/inf questions
