leftbox(f(x), x=a..b, <plot options>)
leftbox(f(x), x=a..b, n, 'shading'=<color>, <plot options>)
algebraic expression in x
variable of integration
left bound of integration
right bound of integration
(optional) indicates the number of rectangles to use
indicates the color used to shade the rectangles
(optional) additional plot options, see ?plot,options

The function leftbox 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 left side of each interval.
Four intervals are used by default.
The formula for the corresponding numerical approximation to this integral is generated by the Maple procedure leftsum. It can be computed by using the procedure value or evalf.
The command with(student,leftbox) allows the use of the abbreviated form of this command.
