▷Riemann Sums – Step by Step – with the TiNSpire CX CAS: Calculus Made Easy

Say you need to compute Riemann Sums at selected points over a given interval. And you do have your trusty TiNspire CX on you. Then start Calculus Made Easy , go to option 1 J in the menu and enter

  1. the given function
  2. the given interval
  3. the selected x-values c1, c2, ..

as shown in image


Then each Riemann rectangle is computed step by step as shown below :

Lastly, view the final Riemann Sum and compare it to the exact definite integral. Pretty close 😉
