WebIntegration can be used to find areas, volumes, central points and many useful things. It is often used to find the area underneath the graph of a function and the x-axis. The first rule to know is that integrals and derivatives are opposites! Sometimes we can work out an integral, because we know a matching derivative. WebYou can evaluate this yourself by taking the definite integral from. [-2, 2] of. (x+2) dx. and you will see that your end result (whether or not you take the absolute value of it) will give you. 8. for the area. This makes sense because the x-intercept of. x+2.
