The King's Property of Definite Integrals (reflection property).

In this video, I prove the King’s Property of Integration (the reflection property)

int_a^b f(x) dx = int_a^b f(a+b-x) dx.

You’ll see a quick substitution proof, then a clean graphical explanation showing why the area stays the same when we reflect across the midpoint (a+b)/2.

Perfect for simplifying tricky definite integrals.
