Explore the connection between definite integrals and areas under a curve
Definite integrals can be used to find the area under a curve
If the area is above the x-axis then the definite integral is exactly the area
If the area is below the x-axis the definite integral will come out negative but the negative is dropped when stating the area
Areas can be used to evaluate definite integrals but you should keep in mind whether the area is above or below the x-axis
