student(deprecated)/integrand - Maple Help

student

 integrand
 locate the integrand of an inert integral
 summand
 locate the summand of an inert sum

 Calling Sequence integrand(expr) summand(expr)

Parameters

 expr - any algebraic expression

Description

 • Important: The student package has been deprecated. Use the superseding commands, Student[Calculus1][Integrand] and Student[Calculus1][Summand], instead.
 • The integrand and summand commands are used to extract the integrand (summand) from an unevaluated integral (sum) respectively.
 • If expr is not an unevaluated integral or sum, but contains one or more such integrals (sums), then the set of integrands (summands) is returned.
 • If several or no integrands (summands) are found the result will be a set.
 • The command with(student,integrand) allows the use of the abbreviated form of this command.
 • The command with(student,summand) allows the use of the abbreviated form of this command.
