Area above the xxx-axis contributes [ ], while area below the xxx-axis contributes negatively to a definite integral.
If f(x)≥g(x)f(x)\ge g(x)f(x)≥g(x) throughout [a,b][a,b][a,b], the enclosed area is
A=∫ab(f(x)−g(x)) dx \boxed{A=\int_a^b\left(f(x)-g(x)\right)\,dx} A=∫ab(f(x)−g(x))dx.
Solve f(x)=g(x)f(x)=g(x)f(x)=g(x).
Area above the xxx-axis contributes positively, while area below the xxx-axis contributes negatively to a definite integral.
