- SlopeField[ <f(x,y)> ]
- Plots a slope field for the differential equation \frac{dy}{dx}=f(x,y)
- Example:
SlopeField[x+y]plots the slope field.
- SlopeField[ <f(x,y)>, <Number n> ]
- Plots a slopefield for the differential equation \frac{dy}{dx}=f(x,y) on an n by n grid (if the Graphics View is square) or a smaller grid if not. Default is 40.
- SlopeField[ <f(x,y)>, <Number n>, <Length Multiplier a> ]
- Plots a slopefield for the differential equation \frac{dy}{dx}=f(x,y). The Length Multiplier 0<a≤1 determines how long the segments are.
- SlopeField[ <f(x,y)>, <Number n>, <Length Multiplier a>, <Min x>, <Min y>, <Max x>, <Max y> ]
- Plots a slopefield for the differential equation \frac{dy}{dx}=f(x,y) inside the specified rectangle (rather than filling the Graphics View)
Note: Use the following tools: 
Move Graphics View, 
Zoom In, 
Zoom Out and observe the effect.
Move Graphics View, Zoom In, Zoom Out and observe the effect.
