Explanation Definition used 1: “Let f be the function defined on a closed interval [ a , b ] , which is divided into n subintervals of equal length Δ x . If x k * is a point in the k th subinterval [ x k − 1 , x k ] , for k = 1 , 2 , .... n , then the Riemann sum for f on [ a , b ] is ∑ k = 1 n f ( x k * ) Δ x . Definition used 2: The limit definition of the definite integral is given by ∫ a b f ( x ) d x = lim n → ∞ ∑ k = 1 n f ( x k * ) Δ x . Theorem: Fundamental theorem of calculus : “If f is continuous on [ a , b ] and F is any anti-derivative of f on [ a , b ] , then ∫ a b f ( x ) d x = F ( b ) − F ( a ) ”. Given: The definite integral ∫ 0 2 ( x 2 − 4 ) d x . Calculation: According to the given data, a = 0 and b = 2 . Divide the interval [ 0 , 2 ] into n equal subintervals. Calculate the length of the each subinterval as follows. Δ x = b − a n = 2 − 0 n = 2 n Therefore, the length of each sub interval is, Δ x = 2 n . By the definition, Right Riemann sum if x k * = a + k Δ x . That is, x k * = 0 + k 2 n x k * = 2 k n Consider ∑ k = 1 n f ( x k * ) Δ x (1) By the above information, the equation (1) can be calculated as follows. ∑ k = 1 n f ( x k * ) Δ x = ∑ k = 1 n ( ( 2 k n ) 2 − 4 ) 2 n = ∑ k = 1 n ( 4 k 2 n 2 − 4 ) 2 n = ∑ k = 1 n ( 8 k 2 n 3 − 8 n ) = 8 n 3 ∑ k = 1 n k 2 − 8 n ∑ k = 1 n 1

(Drag and drop the missing words) An is the of a definite integral as an endpoint of the interval of integration approaches either a specified real number or positive or negative . Although the integral da is , the integral da is improper. In this case, we define the improper integral as a limit dr de lim In general, an improper integral if the limit defining it Thus for example dx does not .It is possible for an improper integral to to infinity. For instance, 00 dr dr = lim C00 is However, there are many improper integrals which diverge in no particular direction, such as z sin zdr oscillates infinity diverge divergent Riemann integral infinite integral exists converge definite integral improper integral limit converges not improper zero 一”
