Plot 3D Parametric Equations

1. Click on "3D" graph in Draw Attributes.
2. Click on "Parametric" check box to select it. This will show two yellow text boxes that start with x=, y= and z= (if Cartesian is selected).
3. Type in a three functions such as: x=3u+1, y=v^2 and sin(v+u) (no need to type x=, y= or z=)
   • You may use u and v variables.
