Now that we in India have approximate 2n factorial formula; and now that we in India have approximate (a/b)^n formula; and now that we have the next number approximation; and now that we have many other formulas for approximate functions: . . . . . . it is time that Indian mathematicians apply their brain and work towards approximate integral.
Just as Taylor series gives function as infinite series of to the power n, factorial and next level derivative; I am suggesting a function of approximations with my approximate values of (a/b)^n, (2n)! and next number.
PM Narendra Modi should form a high power mathematics committee to explore, try and make approximate integral statements.
The benefits are Indian people will develop to behave approximately. Indian people will improve intelligence. Indian people will develop devotion.
If you think my idea is even 10 percent feasible, do comment below.
