Explanation Result used: The Taylor series at 0 for f ( x ) = e − x is e − x = 1 − x + 1 2 ! x 2 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x n + ⋅ ⋅ ⋅ . Theorem used: Error Estimation for Alternating Series If x 0 is a number in the interval of convergence for f ( x ) = a 0 + a 1 x + a 2 x 2 + ⋅ ⋅ ⋅ + a k x k + ⋅ ⋅ ⋅ and the terms in the series f ( x 0 ) = a 0 + a 1 x 0 + a 2 x 0 2 + ⋅ ⋅ ⋅ + a k x 0 k + ⋅ ⋅ ⋅ are alternating in sign and decreasing in absolute value, then the error in the approximation f ( x 0 ) ≈ a 0 + a 1 x 0 + a 2 x 0 2 + ⋅ ⋅ ⋅ + a n x 0 n is strictly less than the absolute value of the next term. That is, | R n ( x 0 ) | < | a n + 1 x 0 n + 1 | . Calculation: The given integral is ∫ 0 0.8 x 4 e − x 2 d x . Let z = x 2 . Substitute z = x 2 in f ( x ) = e − x 2 , that is, f ( z ) = e − z . Since the Taylor series at 0 for e − x = 1 − x + 1 2 ! x 2 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x n + ⋅ ⋅ ⋅ , then the value of f ( z ) is f ( z ) = 1 − z + 1 2 ! z 2 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! z n + ⋅ ⋅ ⋅ . Replace z by x 2 in f ( z ) = 1 − z + 1 2 ! z 2 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! z n + ⋅ ⋅ ⋅ and simplify it as follows. f ( x ) = 1 − x 2 + 1 2 ! ( x 2 ) 2 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! ( x 2 ) n + ⋅ ⋅ ⋅ = 1 − x 2 + 1 2 ! x 4 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + ⋅ ⋅ ⋅ Multiply each term of the series e − x 2 = 1 − x 2 + 1 2 ! x 4 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + ⋅ ⋅ ⋅ by x 4 and simplify as follows. x 4 e − x 2 = x 4 ( 1 − x 2 + 1 2 ! x 4 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + ⋅ ⋅ ⋅ ) = x 4 − x 2 + 4 + 1 2 ! x 4 + 4 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + 4 + ⋅ ⋅ ⋅ = x 4 − x 6 + 1 2 ! x 8 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + 4 + ⋅ ⋅ ⋅ Integrate on both sides of the equation x 4 e − x 2 = x 4 − x 6 + 1 2 ! x 8 − ⋅ ⋅ ⋅ + ( − 1 ) n n ! x 2 n + 4 + ⋅ ⋅ ⋅
