• Alias: int. • Compound operator with built-in evaluation rules. • fx is by default interpreted as Integrate[f,x]. • fx is by default interpreted as Integral[f,x,a,b]. a and b must appear as a subscript and superscript, respectively. • abx is by default output as (ab)x whenever is an operator with a precedence lower than . • Note the use of , entered as dd or \[DifferentialD], rather than ordinary d. • See also: \[ContourIntegral] .
