## X is for x (as an independent variable)

“What is the meaning of life?” This question has been an eternal unsolved problem in philosophy of life. One of mathematicians applied the knowledge of math to tell us what the meaning of life is. However, I still did not know how it connects to the understanding of the meaning of life. I hope that someone can help with this explanation.

Supposing that we make “life” as a letter “f”, “the meaning” is x, and “what” is A. So their functional relation will be f (x) =A. Because different people have different perspectives of meaning of life, the more people we have, the more perspectives we have. At this time, the perspectives of meaning of life will arrive at the limit. According to Calculus Definition of limit, the theorem is going will be:

Limf (x) = A, so Limf (x) = KA (K is a constant)

x —-a                 x —- a

x→∞                   x→∞

That means: when the independent variable (x) tends to be the infinite, the limit of function K f (x) will be equal to KA if we take A as the limit for the function f (x). The conclusion will be: the limit of KA is Kf (x)’s value of function. That’s how the mathematician comes up with this equation: the meaning of life = its limit.
