Properties Of Limits

Some of the important formula and its properties are given below.
1. The limit of constant function is constant.

i.e. lim (C) = C x→a

2. Constant times the limit of the function is equal to the product of constant times the limit of the function.

i. e. lim kf(x) = k lim f(x) x→a x→a
3.Sum or difference Rule:

i.e.     lim [f(X)± g(x)] = lim f(x) ± lim g(x)
x→a x→a x→a

4. Product Rule:
 lim [f(x)  g(x)]  = lim f(x) lim g(x)
x→a x→a x→a

5.Quotient Rule:
  lim [f(x) ➗ g(x)]  = lim f(x)➗ lim g(x)
x→a x→a x→a
