## anonymous 5 years ago does anyone know how to find the definite integral on a ti 83? ex) 100 pi integral symbol (1-1/r+1) dr limits 0,10000

There's an fnint under Math somewhere, I believe. It takes in 4 inputs. The first input is your equation in symbolic form (so 100$$\pi$$(1-1/(x+1))) in this case. The second is the symbol you're integrating against (so just a plain x). The last two inputs are the bounds (so 0 and 10000).
