The Meaning of Integration

Thomas Rike
Organization: Oakland High School
Department: Mathematics Department
Education level


This lesson helps students understand the meaning of integration, including:
  • Integration can be used to find area under a curve. The value of the integral is an area if the integrand is always nonnegative on an interval.
  • Integrals can also have a value which is negative or zero.
  • Integrals can be evaluated by using the geometric interpretation of the integral to simplify the calculations in some cases.
  • The integral can be used to find the average value of a function over an integral.
  • Symmetry can be used to simplify integrals.
  • Integration can be used to accumulate a rate of change.
  • An integral can be used to find the value of a function at a point.
  • An Integral can be used to define a new function.
  • The integral is an infinite sum of products. (Riemann Sum)
