Infinity is the largest real number greater than any other real number.
Since we cannot express its value as a number, we denote it by ∞.
see 10^30, 10^100, 10^(10^(10^10)) numbers increase
as x becomes smaller and smaller 1/x approaches infinity.
like 1/10^-100, 1/0.1^(10^10(10^10))
like this we increase the power of 0.1 then denominator decreases. Then the value of fraction approaches infinity.
1/f = 1/ u + 1/v
if image is formed for a concave mirror at focus, then v = f.
then 1/f = 1/u + 1/f
=> 1/u = 0 then u = ∞
