Tim, for approximate answers we can use NIntegrate NIntegrate[Sqrt[Tan[x]],{x,0,1}] 0.727298 We can increase the accuracy, for example NIntegrate[Sqrt[Tan[x]],{x,0,1}, WorkingPrecision->35] 0.7272982493435106435530637 Accuracy[%] 25 You can find more about NIntegrate from the Help Browser -- Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565 "Tim 9-23" <bendoftimeb at stny.rr.com> wrote in message news:9j8nqi$5qf$1 at smc.vnet.net... > How do I just get the approx. of this, say 5 decimal places? > Mathematica gives an exact answer which is in terms of multiple > fractions, roots, and complex numbers. > > According to my TI-85, it is approx. 0.7273 > > My email address is anti-spammed.
