Explanation Definition used: 1. “If f is continuous on ( − ∞ , c ] , then ∫ − ∞ c f ( x ) d x = lim b → − ∞ ∫ b c f ( x ) d x .” 2. “If f is continuous on [ c , ∞ ) , then ∫ c ∞ f ( x ) d x = lim b → ∞ ∫ c b f ( x ) d x .” 3. Let a function f be continuous over the unbounded interval ( − ∞ , ∞ ) . Let c be any real number, and suppose that both the improper integral ∫ − ∞ c f ( x ) d x and ∫ c ∞ f ( x ) d x are convergent. Then the improper integral of f over ( − ∞ , ∞ ) is defined as ∫ − ∞ ∞ f ( x ) d x = ∫ − ∞ c f ( x ) d x + ∫ c ∞ f ( x ) d x , If anyone of the right hand side is divergent then ∫ − ∞ ∞ f ( x ) d x is divergent. Calculation: The improper integral is ∫ − ∞ ∞ e − | x | d x . The integrand f ( x ) = e − | x | is infinite function on the interval of integration ( − ∞ , ∞ ) . In order to find the above integral, first evaluate the ∫ − ∞ 0 e − | x | d x and ∫ 0 ∞ e − | x | d x . Find the limit of the given improper integral to check whether it is convergent or divergent
