Evaluate the Integral
Problem
Solution
Identify the function to be integrated as
ƒ(x)=sin(x*e^(x^2)) Determine the symmetry of the function by substituting
−x forx Evaluate the function at
−x ƒ*(−x)=sin((−x)*e^((−x)^2))=sin(−x*e^(x^2)) Apply the property of the sine function, which is an odd function, meaning
sin(−θ)=−sin(θ) Conclude that
ƒ*(−x)=−sin(x*e^(x^2))=−ƒ(x) which proves thatƒ(x) is an odd function.Apply the integral property for odd functions over a symmetric interval
[−a,a] which states that(∫_−a^a)(ƒ(x)*d(x))=0
