Unit Eight: Applications of Integration- essential knowledge

What is the formula for the average value of a continuous function f over an interval [a,b]

The average value of a continuous function f over an interval [a,b] is given by: 1/b−a∫abf(x) dx

What does the definite integral of speed represent for a particle in rectilinear motion over an interval of time?

The definite integral of speed represents the particle's total distance traveled over the interval of time.

What does a function defined as an integral represent?

A function defined as an integral represents an accumulation of a rate of change.

What does the definite integral of the rate of change of a quantity over an interval give?

The definite integral of the rate of change of a quantity over an interval gives the net change of that quantity over that interval

How can the definite integral be used in applied contexts?

The definite integral can be used to express information about accumulation and net change in many applied contexts.

How can areas of regions in the plane be calculated?

Areas of regions in the plane can be calculated with definite integrals.

Can areas of regions in the plane be calculated using functions of either x or y?

Yes, areas of regions in the plane can be calculated using functions of either xxx or yyy.

How can areas of certain regions in the plane be calculated?

Areas of certain regions in the plane may be calculated using a sum of two or more definite integrals or by evaluating a definite integral of the absolute value of the difference of two functions.
