Math Problem Statement

If f is integrable on the [a, b], then we define ∫_b^a f(x) dx = - ∫_a^b f(x) dx. True or False?

Solution

The statement in the image is True.

In integral calculus, the property of definite integrals states that:

baf(x)dx=abf(x)dx.\int_b^a f(x)\,dx = -\int_a^b f(x)\,dx.

This means that swapping the limits of integration introduces a negative sign. If you integrate from bb to aa, it's equivalent to integrating from aa to bb with a minus sign. Therefore, the definition given is correct.

Tip: Always pay attention to the limits of integration, as reversing them changes the sign of the result.
