TI 89 and integrals



I've found that sometimes, the TI-89 gives absurd answers that are
right.  For example, if I take the integral of (tan x)^6*(sec x)^2 the
answer should be 1/7*(tan x)^7 However, the calculator pumps out some
long and complex value.  Nevertheless, it is equivilent to the answer.
Does anyone know how to get the condenced value?  And no, tCollect
didn't do it.Hmm.
