perfect! thanksJustin Lazear said:Since you make me actually find my 83 from the giant stack of crap on my desk...
Go to the Y= menu, set a function into Y1. Then, press 2nd / TRACE (CALC) / 7: [itex]\int [/itex]f(x)dx. It will take you to the graphing screen and ask you for the boundaries. Put them in, and it spits out the answer at the bottom of the screen.

A definite integral is a mathematical concept used to find the area under a curve between two points on a graph. It is represented by the symbol ∫ and is calculated by taking the limit of a sum of infinitely small rectangles under the curve.
The TI-83 Plus is a graphing calculator commonly used in high school and college math and science classes. It is manufactured by Texas Instruments and can perform various calculations, graph functions, and solve equations.
To solve a definite integral on the TI-83 Plus, you can use the "fnInt" function. First, enter the function you want to integrate into the "Y=" menu. Then, go to the "fnInt" function under the "MATH" menu and input the function, the variable, and the lower and upper bounds. Press enter and the calculator will give you the value of the definite integral.
The TI-83 Plus can only solve definite integrals that have an analytical solution, meaning it can be expressed using a finite combination of elementary functions. It cannot solve integrals that require advanced techniques such as integration by parts or substitution.
Yes, the TI-83 Plus can be used to check your work when solving definite integrals. You can compare the value given by the calculator to the one you calculated by hand to check for errors. Keep in mind that the calculator may round its answer, so there may be a slight difference in the values.
