 rightbox
 graph an approximation to an integral

 Calling Sequence rightbox(f(x), x=a..b, ) rightbox(f(x), x=a..b, n, 'shading'=, )

Parameters

 f(x) - algebraic expression in x x - variable of integration a - lower bound of range of integration b - upper bound of range of integration n - (optional) indicates the number of rectangles to use color - indicates the color used to shade the rectangles plot options - (optional) additional plot options, see ?plot,options

Description

 • Important: The student package has been deprecated. Use the superseding command Student[Calculus1][RiemannSum] instead.
 • The function rightbox will generate a plot of rectangular boxes used to approximate a definite integral.  The height of each rectangle (box) is determined by the value of the function at the right side of each interval.
 • Four equal-sized intervals are used by default.
 • The value of the corresponding numerical approximation can be obtained by the Maple procedure rightsum.
 • The command with(student,rightbox) allows the use of the abbreviated form of this command.
