Given f(x) =

(i)To find

To limit to exist, we know …….(1)

Thus to find the limit using the concept ……(2)

……..(3)

……(4)

…….(5)

From above equations

thus the limit exists

Thus from (5)

(ii) To find

To limit to exist, we know …….(1)

Thus to find the limit using the concept ……(2)

……..(3)

……(4)

From above equations

Thus from (2),(3) and (4)
