The bug me...Thanks for being a fan of our products. The bug mentioned here was fixed over a year ago, in open communication with the users who reported it. For more details, please see the response from Daniel Lichtblau in the Wolfram Community: http://community.wolfram.com/groups/-/m/t/374658?p_p_auth=qBppEnx7. The issue with ClebschGordan returning a symbolic result that is invalid for some values of the symbolic parameter is one we are aware of. It is a limitation in the restrictions we use in the symbolic form of the function. We will consider extending this to give a complete set of conditions for validity after numeric substitution.Brittany Banks, Wolfram Researchnoreply@blogger.comtag:blogger.com,1999:blog-3360583082244632912.post-3542910547340058452016-04-20T10:56:14.789+02:002016-04-20T10:56:14.789+02:00Sorry, there should be Abs[] of the sum of exponen...Sorry, there should be Abs[] of the sum of exponent.

Another example given there: Integrate[Sqrt[(2t)^2+(4-3t^2)^2],{t,0,2}]//N gives the complex number 0.881679+1.17073i, although in reality the integrand (2t)^2+(4-3t^{2})^{2}>0 is a positive number for 0<=t<=2.
