Removable discontinuity, jump and essential discontinuities.

Prove that
a- if lim f(x) as x->c exists but has a value different from f(c) the discontinuity at c is called removable,
b-if lim f(x) as x->c^+ not =lim f(x) as x->c^-, then f has a jump discontinuity at c,
c-if lim f(x) as x->c does not exists for some other reason the discontinuity at c is called essential discontinuity.
