What This Question Tests

This problem evaluates a definite integral by splitting the integrand and using properties of odd and even functions over a symmetric interval.

Concepts Tested

Definite integral as sum/difference of functionsProperties of odd and even functions

Formulas Used

∫-a to a f(x)dx = 0 if f(x) is odd

∫-a to a f(x)dx = 2 ∫0 to a f(x)dx if f(x) is even
