# PlotPoints

 PlotPointsis an option for plotting functions that specifies how many initial sample points to use.
• With a single variable, PlotPoints->n specifies the total number of initial sample points to use.
• With more than one variable, PlotPoints->n specifies that n initial points should be used in each direction.
• PlotPoints->{n1, n2, ...} specifies different numbers of initial sample points for each successive direction.
• The initial sample points are usually equally spaced.
• Adaptive procedures controlled by MaxRecursion are used to choose more sample points.
Use 10 points in each direction:
MaxRecursion will cause additional sampling beyond the initial 10 points:
Use 50 points along the direction:
Use different numbers of points for different variables:
Use 10 points in each direction:
 Out[1]=
