Finally, rational functions involving trigonometric or hyperbolic functions can be integrated. With an argument (@kbd{C-u a i}), this command will compute the definite integral of the expression on top of the stack. In this case, the command will again prompt for an integration variable, then prompt for a lower limit and an upper limit. @ifinfo If you use the @code{integ} function directly in an algebraic formula, you can also write @samp{integ(f,x,v)} which expresses the resulting
