int( f, ‘m’, ‘n’): Returns the integral of the expression f with respect to the default independent variable
evaluated over the interval [m, n], where m and n are numeric expressions.
The other symbolic functions for pedagogical and graphical applications, conversions, integral transforms,
and linear algebra are summarized in Tables 1.38 to 1.42.
