7.5 Area Between Curvesap Calculus
  • Question 5: Explain the area under the curve? Answer: The area under a curve that exists between two points can be calculated by conducting a definite integral between the two points. To calculate the area under the curve y = f(x) between x = a & x = b, one must integrate y = f(x) between the limits of a and b.
  • The calculator will find the area between two curves, or just under one curve. Show Instructions In general, you can skip the multiplication sign, so `5x` is equivalent to `5.x`.
  • Be able to nd the area between the graphs of two functions over an interval of interest. Know how to nd the area enclosed by two graphs which intersect. PRACTICE PROBLEMS: 1. Let Rbe the shaded region shown below. (a) Set up but do not evaluate an integral (or integrals) in terms of xthat represent(s) the area of R.
  • By integrating the difference of two functions, you can find the area between them. Created by Sal Khan.Practice this lesson yourself on KhanAcademy.org righ.
