Dear Naman,

Some limits will need simplification before they can be solved:

If direct substitution yields 0/0, undefined, you have to factor & reduce.

Lim x2 - 4

x →2 x - 2

The limit exists even though the function is undefined. The limit for this example is 4.

To solve an undefined limit, 

 direct substitution yields ∞/∞, undefined, then divide by the highest power.

lim 3x + 1

x→∞ 5x + 6

The limit exists even though the function is undefined. The limit for this example is 3/5.

To solve an undefined limit 

 

Best Of luck
