 Lineint
 inert Form of Line Integral

 Calling Sequence Lineint(f(x,y), x, y) Lineint(f(x,y), x=x(t), y=y(t)) Lineint(f(x,y), x, y =a..b) Lineint(f(x,y,z), x, y, z)

Parameters

 f(x, y) - expression in x and y a, b - (optional) lower and upper bounds

Description

 • Important: The student package has been deprecated. Use the superseding command Student[VectorCalculus][LineInt] instead.
 • This two-dimensional version of the procedure constructs a line integral'' of f(x,y) expressed respect to y. In general, the first variables are regarded as parameters of the last.
 • Lineint uses an unevaluated'' form of Maple's int function, and only minor simplifications are performed.
 • A range can be specified for the parameter, as in (z = a..b).
 • Use value to force Lineint to evaluate like int.
 • The command with(student,Lineint) allows the use of the abbreviated form of this command.
