**Abstract.**A complete solution to the problem of symbolic
differentiation and integration of any order (integer, fractional,
or real) of the *power-inverse trigonometric classes* has
been given. In this work, we tackle the *power-inverse
tangential class*

where 's are polynomials of certain degrees. We give a unified
formula for symbolic derivatives and integrals of any order. The
approach does not depend on integration techniques. The formula, in
general, is in terms of the -function, but in many cases can be
simplified for less general functions. Arbitrary (integer,
fractional or real) order of differentiation is found according to
the Riemann-Liouville definition, whereas we adopt the generalized
Cauchy -fold integral definition for arbitrary order of
integration.
