When definite integration is used to find areas, notation like \displaystyle \int_a^b y \, dx is used where the a and b denote the lower and upper limits of the integration.
You must understand clearly how integral notation works. When doing definite integration, use the notation as accurately as you can, including the use of different styles of brackets.
Summary/Background
 A
note about graphic calculatorsA graphic calculator, for example the TI-83 or similar model, can work out definite integrals for you.  First use the Y= screen to enter a function, such as -X²+9x-14Use ZOOM 6 to get a good display of the curve. Select 2nd CALC option 7. Enter the lower and upper limits of the integration as requested on the screen. |
