Visualization:
Using Microcalc:

1. Choose Intermediate Calc from the initial menu and press .
2. Use the arrow keys to move to the menu item Direction Fields, press and .
3. Use the arrow keys to move to the menu item dy/dx = F(x, y), press .
4. At the prompt F(x, y) =, enter the formula sin(x)
5. Enter the bounds at the prompts

   x0 = -2pi

   x1 = 2pi

   y0 = -3

   y1 = 3

   You can enter pi by pressing at the same time.
