Thanks for everyone's help but I still can't seem to get the function out of the Conditional. Here's the actual ConditionalExpression I'm dealing with: x -> ConditionalExpression[(1/\[Pi]) 105 (-2 ArcTan[\[Sqrt]Root[ 1 - 4584 #1 + 525588 #1^2 - 24932888 #1^3 + 643774850 #1^4 - 10134675448 #1^5 + 103523895748 #1^6 - 713980114440 #1^7 + 3417573832943 #1^8 - 11577472180368 #1^9 + 28132792718632 #1^10 - 49450791062896 #1^11 + 63131885232924 #1^12 - 58540019029360 #1^13 + 39271847011624 #1^14 - 18902427543696 #1^15 + 6437818513647 #1^16 - 1518441755144 #1^17 + 239987843524 #1^18 - 24146287608 #1^19 + 1422915970 #1^20 - 42378776 #1^21 + 478484 #1^22 - 1512 #1^23 + #1^24 &, 1]] + 2 \[Pi] C[1]), C[1] \[Element] Integers] Using the various suggestions the closest I can get is the error statement ...

Thanks in advance for any additional clues. Cheers, Scott
