Using Microcalc:

- Choose
*Beginning Calculus*from the initial menu and press . - Use the arrow keys to move to the menu item
*Riemann Sum*, press and . - At the prompt
*F(x) =*, enter the formulasin(x) - Enter the bounds at the prompts
*x_0 =*0*x_1 =*pi

- Use the arrow keys to move to the menu item
*Lower Riemann Sum*, press . - At the prompt,
*N =*, enter 12 . - You then see the following:
- Press and you will see the approximation using Lower Riemann Sums.
- Press again.
- Use the arrow keys to move to the menu item
